Question

how many electrons needed to phosphorus to get stable?​

Answer 1

phosphorus needs 3 electrons to get stable

Answer 2

Answer: Simple answer to this question will be 3 (if you are in class 10 CBSE) because the Bohr E.C. is 2,8,5

Explanation: But if you have higher knowledge then you must know about the expanded octet rule.

Expanded octet : A case where an atom shares more than eight electrons with its bonding partners.

Phosphorus pentachloride: In the PCl5 molecule, the central phosphorus atom is bonded to five Cl atoms, thus having 10 bonding electrons and violating the octet rule. The overall geometry of the molecule is depicted (trigonal bipyramidal), and bond angles and lengths are highlighted.

Phosphorus pentachloride (PCl5) and sulfur hexafluoride (SF6) are examples of molecules that deviate from the octet rule by having more than 8 electrons around the central atom.
