The basis of chemistry as a science is the Periodic Table of Dmitry Mendeleyev.
The main topics of the school chemistry course include the study of the structure of the atom, chemical bonds, properties of substances, chemical reactions and their classification, as well as the main classes of inorganic and organic compounds. An important part is familiarization with the basic laws of chemistry and the periodic table of elements.
Basic concepts and laws of chemistry:
- Substance, chemical element, atom, molecule, ion.
- Simple and complex substances, chemical bond.
- Chemical reactions: types, equations, calculations using equations.
- Basic laws of chemistry (law of conservation of mass, law of constancy of composition, etc.).
Structure of matter:
- Atomic structure: atomic nuclei, electrons, electron shells.
- Periodic table of chemical elements: patterns of change in the properties of elements.
- Chemical bonding: ionic, covalent, metallic.
Classification of substances:
- Inorganic substances: oxides, acids, bases, salts.
- Organic substances: hydrocarbons, alcohols, acids, ethers and others.
Chemical properties and production of substances:
- Properties of oxygen, hydrogen, water.
- Properties of metals and non-metals.
- Obtaining and using substances in various fields.
Organic Chemistry:
- Main classes of organic compounds, Theory of chemical structure of organic substances, Isomerism and homology.
Chemistry and Life:
- The relationship of chemistry with other sciences and practical activities.
- The role of chemistry in solving environmental problems.
This list provides a general idea of the main topics of the school chemistry course. Depending on the class and textbook, the topics may be presented in different order and with different depth of study, say education experts.
