The Composition of Compounds and the Property of Atoms

The composition of compounds depends on the properties of atoms. The specific property that determines the composition of compounds is the valence of atoms. The valence of an atom refers to its ability to form chemical bonds with other atoms. It determines the number of electrons an atom can gain, lose, or share in order to achieve a stable electron configuration.

Atoms with the same valence tend to have similar chemical properties and can form compounds with other atoms that have complementary valences. For example, atoms with a valence of 1, such as hydrogen (H), can form compounds with atoms that have a valence of -1, such as chlorine (Cl), to create the compound hydrogen chloride (HCl).

The valence of an atom can be determined by its position in the periodic table. Elements in the same group or column of the periodic table tend to have similar valences. For example, all elements in Group 1 (the alkali metals) have a valence of +1, while elements in Group 17 (the halogens) have a valence of -1.
