Answer 1

Answer : The correct option is, $1s^22s^22p^63s^23p^64s^23d^{10}4p^5$

Explanation :

The given element bromine belongs to the group 17 and period 4. The symbol of bromine is, Br.

The atomic number of bromine = 35

The total number of electrons present in bromine element = 35

Electronic configuration : It is defined as the arrangement of electrons around the nucleus of an atom.

Hence, the correct electronic configuration of bromine is,

$1s^22s^22p^63s^23p^64s^23d^{10}4p^5$

Answer 2
