Question

The total number of electrons present in all the p-orbital of bromine are (Given: Atomic no. of $Br=35$)

• A. 5
• B. 15
• C. 17
• D. 35

Answer 1

Answer: (C)

Electronic configuration of bromine is

$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^5$

Then; the total no. of p-electron in bromine is $17.$
