The valency of phosphorus is 3, 5. The number of the phosphorus atom is 15. There are 2,8,5 various electronic setups.

Valency of Phosphorus

When an atom receives three additional electrons, its orbit is complete. or five electrons should be lost by the atoms. The ability of an atom to combine is known as valency. Consequently, the valencies of phosphorus are 3 and 5.

  • The phosphorus atomic number is 15.and [Ne] 3s2 3p2 is its electronic configuration in the ground state.
  • As far as we know, phosphorus also has a free third orbital. In an excited state, electrons are stimulated to transition from a lower to a higher energy level. In the excited state of phosphorus, an electron is excited from the 3s to the 3d orbit. Currently, the electrical arrangement of phosphorus' excited state [Ne]3s13p33d1.
  • We can see that the electrical structure of phosphorus in its excited state contains five unpaired electrons.
  • The ability of an atom to establish bonds with other atoms is referred to as valency.
  • In this excited state, phosphorus possesses five unpaired electrons, allowing it to form five bonds with other elements.
  • The valency of phosphorus in its excited state at that point is 5.

Summary:-

The Valency of Phosphorus is ________. a) 2, 3 b) 3, 4 c) 4, 5 d) 3, 5

3, 5 is the valency of phosphorus. 15 is the number of phosphorus atom and the electronic configuration is 2, 8, 5.
