The bromine atom possesses 35 electrons....

The bromine atom possesses 35 electrons. it contains 6 electrons in 2p-orbital, 6 electrons in 3p-orbital and 5 electrons in 4p-orbital. Which of these electrons experiences the lowest effective nuclear charge?

A

2p

B

3p

C

4p

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
Electronic configuration of Br (35): `1s^(2)2s^(2)2p^(6)3s^(2)2p^(6)3d^(10)4s^(2)4p^(5)`
The electron in 4p are farthest from nucleus thus experience least effective nuclear charge.
