This is known as octet rule OCTET RULE

If two atoms share two pairs of electrons, the covalent bond between them is called a double bond. LEWIS-LANGMUIR THEORY

Pairs of electrons in the valence shell repel one another These pairs of electrons tend to occupy such positions in space that minimise repulsion and thus maximise distance between them. VSEPR THEORY

A multiple bond is treated as if it is a single electron pair. Where two or more resonance structures can represent a molecule, the VSEPR model is applicable to any such structure VSEPR THEORY
