- In chemistry, a 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.
- Phosphonium ion is PH₄+.
- Formal charge can be found by following formula
- Valence electrons- Unbonded electrons- Bonded electrons/2
- Valence electron is an outer shell electron that is associated with an atom.
- Unbonded, non-bonded or lone pair electrons are terms used to describe electrons that surround an atom, but don't play a direct role in bond formation.
- A bonding electron is an electron involved in chemical bonding.
- And formal charge of P is +1 and of Hydrogen is 0.
