Electronic configuration of Br (35): 1 s2 2 s2 2 p6 3 s2 116. 3 p6 3 d10 4 s2 4 p5 The electron in 4 p are farthest from nucleus thus experience least effective nuclear charge.

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

$2 p$

$3 p$

$4 p$

None of these

Electronic configuration of $B r (35) : 1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2}$ 116. $3 p^{6} 3 d^{10} 4 s^{2} 4 p^{5}$

The electron in $4 p$ are farthest from nucleus thus experience least effective nuclear charge.
