Answer

Brief Explanations:

Bromine has an atomic number of 35. The electron - filling order follows the Aufbau principle, Pauli exclusion principle, and Hund's rule. Starting from the 1s orbital and filling in order of increasing energy levels, the correct electron configuration is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{5}$.

Answer:

$1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{5}$ (the first option)
