Question

how to find hybridization of a given molecule?

Answer 1

You can find the hybridization of an atom by finding its steric number: The steric number = the number of atoms bonded to the atom + the number of lone pairs the atom has. If the steric number is 4, the atom is s p 3 hybridized.

Answer 2

valence electron
monovalent atom
cation
anion
cation and anions are charge present
