Inorganic chemical compounds
Explanation:
Inorganic chemical compounds employ the use of oxidation numbers of atoms to write their chemical formula.
- The oxidation number is the formal charge assigned assigned to an atom present in a molecule or formula unit or ion based on some rules.
- Knowledge of this number is used in writing the formulae of inorganic compounds.
- These compounds forms by the exchange of certain small whole numbers by atoms or groups of atoms.
- The combining power usually correspond to the number of electrons usually lost or gained or shared by atoms of elements during chemical combinations or the number of positive or negative charges carried by ions.
For example:
A B
combining power(Valency): X Y
Exchange of valencies Y X
Molecular formula of compound ABₓ
