p has at. no. 15 last electron goes into da 3s orbital where does it have empty d orbital for bonding ie backbonding with compounds

dev_22oct

P atomic no 15

electronic configuration: 1s²,2s²,2p⁶,3p⁵,3d⁰

i think nw u can c the vacant d orbitals.

eistien

ther electronic configuration is 1s2 2s2 2p6 3s2 3p3 3d0

obviously it can form bonding to have expanded octect with electrons in d orbital empty fill in electrons in 3d check for PCl5

electronic conf. of p in ground state = 1s²2s²2p⁶3s²3p³3d⁰

electronic conf. of p in excited state = 1s²2s²2p⁶3s¹3p³3d¹

(as it goes sp³d hybridisation).So it has empty d orbital.
