All the substances with which we Simple and complex substances

Simple substances and their classification When studying the material of the previous paragraphs, you have already become acquainted with some substances. So, for example, a hydrogen gas molecule consists of two atoms of the chemical element hydrogen - H + H = H2. Simple substances are substances that contain atoms of the same type. Simple substances, from among the substances known to you, include: oxygen, graphite, sulfur, nitrogen, all metals: iron, copper, aluminum, gold, etc. Sulfur is made up of only atoms of the chemical element sulfur, while graphite is made up of atoms of the chemical element carbon. It is necessary to clearly distinguish between concepts "chemical element" and "simple substance". For example, diamond and carbon are not the same thing. Carbon is a chemical element, and diamond is a simple substance formed by the chemical element carbon. In this case, a chemical element (carbon) and a simple substance (diamond) are called differently. Often a chemical element and a simple substance corresponding to it are called the same. For example, the element oxygen corresponds to a simple substance - oxygen. It is necessary to learn to distinguish where it is an element and where it is a substance! For example, when they say that oxygen is part of water, we are talking about the element oxygen. When they say that oxygen is a gas necessary for breathing, we are talking about a simple substance, oxygen. Simple substances of chemical elements are divided into two groups - metals and non-metals. Metals and non-metals fundamentally different in their physical properties. All metals are solids under normal conditions, with the exception of mercury - the only liquid metal. Metals are opaque, have a characteristic metallic sheen. Metals are ductile and conduct heat and electricity well. Non-metals are not similar to each other in physical properties. So, hydrogen, oxygen, nitrogen are gases, silicon, sulfur, phosphorus are solids. The only liquid non-metal, bromine, is a brown-red liquid. If we draw a conditional line from the chemical element boron to the chemical element astatine, then in the long version of the Periodic System, non-metallic elements are located above the line, and below it - metal. In the short version of the Periodic Table, the non-metallic elements are located below this line, and both the metallic and non-metallic elements are above it. This means that it is more convenient to determine whether an element is metallic or non-metallic using the long version of the Periodic System. This division is conditional, since all elements in one way or another exhibit both metallic and non-metallic properties, but in most cases such a distribution is true.

Compound substances and their classification

If the composition of simple substances includes atoms of only one type, it is easy to guess that the composition of complex substances will include several types of different atoms, at least two. An example of a complex substance is water, you know its chemical formula - H2O. Water molecules are made up of two types of atoms: hydrogen and oxygen. Complex Substances Substances that are made up of different types of atoms Let's do the following experiment. Mix powders of sulfur and zinc. We place the mixture on a metal sheet and set it on fire with a wooden torch. The mixture ignites and quickly burns with a bright flame. After the completion of the chemical reaction, a new substance was formed, which includes sulfur and zinc atoms. The properties of this substance are completely different than the properties of the original substances - sulfur and zinc. Complex substances are usually divided into two groups: inorganic substances and their derivatives; and organic substances and their derivatives. For example, rock salt is an inorganic substance, while the starch found in potatoes is an organic substance.

Structure types of substances

According to the type of particles that make up substances, substances are divided into substances molecular and non-molecular structure. The composition of a substance can include various structural particles, such as atoms, molecules, ions. Therefore, there are three types of substances: substances of atomic, ionic and molecular structure. Substances of different types of structure will have different properties.

Substances of atomic structure

An example of substances of an atomic structure can be substances formed by the element carbon: graphite and diamond. The composition of these substances includes only carbon atoms, but the properties of these substances are very different. Graphite- fragile, easily exfoliating substance of gray-black color. Diamond- transparent, one of the hardest mineral on the planet. Why do substances composed of the same type of atoms have different properties? It's all about the structure of these substances. The carbon atoms in graphite and diamond bond in different ways. Substances of atomic structure have high boiling and melting points, as a rule, they are insoluble in water, non-volatile. Crystal lattice - an auxiliary geometric image introduced to analyze the structure of a crystal

Substances of molecular structure

Substances of molecular structure- These are almost all liquids and most gaseous substances. There are also crystalline substances, the composition of the crystal lattice of which includes molecules. Water is a substance of molecular structure. Ice also has a molecular structure, but unlike liquid water, it has a crystal lattice where all molecules are strictly ordered. Substances of a molecular structure have low boiling and melting points, are usually brittle, and do not conduct electric current.

Substances of ionic structure

Substances of ionic structure are solid crystalline substances. An example of an ionic compound substance is table salt. Its chemical formula is NaCl. As you can see, NaCl consists of ions Na+ and Cl⎺, alternating in certain places (nodes) of the crystal lattice. Substances of an ionic structure have high melting and boiling points, are brittle, as a rule, are highly soluble in water, and do not conduct electric current. The concepts of "atom", "chemical element" and "simple substance" should not be confused.

"Atom"- a concrete concept, since atoms really exist.
"Chemical element" is a collective, abstract concept; in nature, a chemical element exists in the form of free or chemically bound atoms, that is, simple and complex substances.

The names of chemical elements and the corresponding simple substances coincide in most cases. When we talk about a material or component of a mixture - for example, a flask filled with gaseous chlorine, an aqueous solution of bromine, let's take a piece of phosphorus - we are talking about a simple substance. If we say that a chlorine atom contains 17 electrons, a substance contains phosphorus, a molecule consists of two bromine atoms, then we mean a chemical element. It is necessary to distinguish between the properties (characteristics) of a simple substance (a collection of particles) and the properties (characteristics) of a chemical element (an isolated atom of a certain type), see the table below:

Compounds must be distinguished from mixtures, which also consist of different elements. The quantitative ratio of the components of the mixture can be variable, and the chemical compounds have a constant composition. For example, in a glass of tea, you can add one spoonful of sugar, or several, and sucrose molecules С12Н22О11 contains exactly 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms. Thus, the composition of compounds can be described by one chemical formula, and the composition mixture is not. The components of the mixture retain their physical and chemical properties. For example, if you mix iron powder with sulfur, then a mixture of two substances is formed. Both sulfur and iron in this mixture retain their properties: iron is attracted by a magnet, and sulfur is not wetted by water and floats on its surface. If sulfur and iron react with each other, a new compound is formed with the formula FeS, which does not have the properties of either iron or sulfur, but has a set of its own properties. In conjunction FeS iron and sulfur are bound together and cannot be separated by methods that separate mixtures. Thus, substances can be classified according to several parameters: Conclusions from the article on the topic Simple and complex substances

Simple substances- substances that contain atoms of the same type
Elements are divided into metals and non-metals
Complex Substances Substances that are made up of different types of atoms
Compounds are divided into organic and inorganic
There are substances of atomic, molecular and ionic structure, their properties are different
Crystal cell is an auxiliary geometric image introduced to analyze the crystal structure

(1) The old village with its thousand-year history goes into oblivion today. (2) And this means that centuries-old foundations are collapsing, that centuries-old soil on which our entire national culture has grown: its ethics and aesthetics, its folklore and literature, its miracle language, disappears. (3) The village is our origins, our roots. (4) The village is the mother's womb, where our national character was born and developed.

(5) And today, when the old village is living out its last days, we peer with new, special, sharpened attention at the type of person that was created by it, peer at our mothers and fathers, grandfathers and grandmothers.

(6) Oh, a little kind words fell to their lot! (7) But it is precisely on them, on the shoulders of these nameless workers and warriors, that the building of our entire life today stands firmly!

(8) Let us recall, for example, only one feat of a Russian woman in the last war.

(9) After all, it was she, the Russian woman, who opened the second front with her superhuman work back in the forty-first year, the front that the Soviet army so longed for.

(10) And how, by what measure to measure the feat of the same Russian woman in the post-war period, in those days when she, often herself hungry, undressed and undressed, fed and clothed the country, with her true patience and resignation of the Russian peasant woman carried her heavy cross soldier widows, mothers of sons who died in the war!

(13) This is not an idealization of village life and not a longing for the outgoing hut of Russia, as some critics and writers broadcast with thoughtless ease and arrogance, but our filial, albeit belated gratitude.

(1) One day in the winter, an appeal from doctors to the audience sounded from the television screens of Omsk: an injured person urgently needed donated blood.

(2) People sat in warm cozy apartments, no one knew about each other's affairs, no one was going to, and could not control human actions. (3) Any person could later say: I didn’t watch TV, I didn’t hear the appeal. (4) But the majority still had a controller. (5) The highest moral controller is conscience. (6) But that's all! (7) Yes, and only. (8) But this “only”, this only selectivity turned out to be the main one in the following minutes, when a person began to act. (9) On trams, buses, taxis, people got to the hospital. (10) The nurses on duty went out to meet them. (11) 320 people came to the hospital in 30 minutes. (12) The victim was saved.

(13) I wanted to meet at least some of these people. (14) I went into their houses, talked, finding out the motives of the act, painfully looked for words and felt how these words were not enough not only for me, but also for the donors themselves ... (15) I still feel the awkwardness of those conversations, clarifications . (16) After all, the main thing was different. (17) The main thing was and is that these people acted on the basis of their usual ideas about moral duty. (18) They had no other motives. (19) Moral duty is their main motive. (20) The act of these people is not a bright flash, but a norm of behavior, and it was truly absurd to try out the motive for an action aimed at helping a person in trouble.

(21) In fact, it is necessary, first of all, to investigate the moral atmosphere, the environment that allows educating people in such an understanding of a sense of duty, such responsiveness. (22) This is really necessary, because it is important that the manifestation of the humane properties of the human soul become a natural need for everyone. (23) For everyone!

(24) With particular clarity, I remember the faces of my old interlocutors at the moments when their act was characterized by many journalists as a feat. (25) No, these people knew well that a feat is one thing, and the fulfillment of a moral duty is another. (26) The journalist should have known this too. (27) As well as the fact that each of these people, in general, every person who is able to transgress personal well-being in order to help another person, is capable of much more. (28) Just such a person will not allow a collision, a conflict between personal interest and public interest.

(29) One originates in the other. (30) Big - in small, great - in big.
