What kind of subject is chemistry?

Chemistry is a natural science, which mainly studies the composition, properties, structure and changing rules of substances at the molecular and atomic levels, and creates new substances.

Different from particle physics and nuclear physics, chemistry studies the physical structure of atoms ~ molecules ~ ions (groups) and the interaction between chemical bonds and intermolecular forces, and the scale is the closest to the macro in the micro world.

Their natural laws are also closely related to the physical and chemical properties of substances and materials in the macro world of human existence. As an important bridge between the micro and macro material world, chemistry is one of the main ways and means for human beings to understand and transform the material world.

Classification of chemical disciplines:

1, inorganic chemistry

Elemental chemistry, inorganic synthetic chemistry, inorganic polymer chemistry, inorganic solid chemistry, coordination chemistry (that is, complex chemistry), isotope chemistry, bioinorganic chemistry, organometallic chemistry, metalloenzyme chemistry, etc.

2. Organic chemistry

General organic chemistry, organic synthetic chemistry, metal and nonmetal organic chemistry, physical organic chemistry, bioorganic chemistry, organic analytical chemistry.

3. Physical chemistry

Structural chemistry, thermochemistry, chemical thermodynamics, chemical kinetics, electrochemistry, solution theory, interface chemistry, colloid chemistry, quantum chemistry, catalysis and its theory.
