VSEPR THEORY
Electron groups around the central atom will be most stable when they are as far apart as possible. This is called the Valence Shell Electron Pair Repulsion Theory
-
VSEPR NOTATION
In the VSEPR notation used to describe molecular geometries, the central atom in a structure is denoted as A, terminal atoms as X, and the lone pairs of electrons as E

Hybrid Orbitals

-
Oxygen, with two unpaired electrons, usually forms two bonds.
However, carbon, with only two unpaired electrons, generally forms four bonds. For example, methane, CH4, is well known.

Atomic Orbital
Overlap
Valence Bond (VB) Theory states that a covalent bond is formed by the pairing of two electrons with opposing spins in the region of overlap of atomic orbitals between two atoms
