Question

formal charge of phosphorus atom in PO4 3- ion​

Answer 1

• Formal charge on Phosphorus atom in PO₄³⁻ is zero.
• Formal charge can be found by using the following formula

Formal charge = Valence electrons- Unbonded electrons- Bonded electrons/2

• Where, Valence electron is the electrons present in the outer shell of an atom.
• Unbonded electrons are also known as lone pair of electrons, they don't play a direct role in bond formation.
• And a bonding electrons is the electrons which play a role in bond formation.

For P in PO₄³⁻

Formal charge = 5 - 0 - 10/2 = 0
