Answer:
Group 5th A.
Step-by-step explanation:
The elements of group 5th A shows the electronic configuration of s² p³.
This group consist of nitrogen, phosphorus, arsenic, antimony, bismuth.
Electronic configuration of nitrogen:
N₇ = [He] 2s² 2p³
Electronic configuration of phosphorus
P₁₅ = [Ne] 3s² 3p³
Electronic configuration of arsenic
As₃₃ = [Ar] 3d¹⁰ 4s² 4p³
Electronic configuration of antimony
Sb₅₁ = [Kr] 4d¹⁰ 5s² 5p³
Electronic configuration of bismuth
Bi₈₃ = [Xe] 4f¹⁴ 5d¹⁰ 6s² 6p³
