explain simply the total account of hybridisation, and its methods briefly?

hey student..
In chemistry, hybridisation (or hybridization) is the concept of mixing atomic orbitals into new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory. Hybrid orbitals are very useful in the explanation of molecular geometry and atomic bonding properties.
also the formula can be
1/2 ( V + M - C + A )

V = Number of valence electrons
M = Monoatomic atoms bonded to central atom
C = Cationic charge
A = Anionic charge
