nvs = FC+(nbp/2)+nnb
This formula uses 4 Variables
Variables Used
No. of Valence Shell Electrons - The No. of Valence Shell Electrons of an atom are outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond.
Formal Charge - The Formal Charge is the charge assigned to an atom in a molecule, assuming that electrons in all chemical bonds are shared equally between atoms, regardless of relative electronegativity.
No. of Bonding Pair Electrons - The No. of Bonding Pair Electrons is the number of electrons shared in a bond.
No. of Non-Bonding Pair Electrons - The No. of Non-Bonding Pair Electrons in the valence shell are the ones not taking part in the bond formation.

Number of Valence Electrons given Formal Charge Formula

No. of Valence Shell Electrons = Formal Charge+(No. of Bonding Pair Electrons/2)+No. of Non-Bonding Pair Electrons
nvs = FC+(nbp/2)+nnb

Is formal charge the same as charge or partial charge?

A formal charge has a value of either a positive integer, a negative integer, or zero. A partial charge usually has a positive or negative non-integer. Each atom in a molecule has both, able to calculate the formal charge. A formal charge indicates gain or loss of electron(s) while forming covalent bond(s). A partial charge indicates which atom in a bond have a higher electronegativity and which have a lower electronegativity.
