Give the spectroscopic notation (also called spdf notation) electron configuration of Br.
Enter the subshells in the order in which they are filled.
For example, for oxygen, the answer would be: 1522s22p4.

Answer

-
And as
fisst find out the atomic No. ot given element (B9 = 35)
Next follow Aufbay Principle-energy order (15, 25, 2P...)
Fill the subshell with their maximum cerpacity
(5=2, P=6, d = 10 + = 14)
then write all electronic contigoration and e filled in
orbital (e.g. - 15² 25²...)
= electronic contiguration of Brit
energy order
for Aufbau Principle
& 15 25 2P+35 345 3d 4P55
40 50 65 & 4f 5d & GP. T 7d.
1) Atomic no. of Br = 5 (Total No. of ě has 35)
2) energy order for Br= 15+257 2P 35 3P 453 49
3) on By no charge That's why Atomic No. = No. of e-
Br =
15² 25 21 8 35² 3p 4² 3d 4p5
