(b) 4s, 3d, 4p, 5s, 4d
(c) 5s, 4p, 3d, 4d, 5s
(d) 3d, 4p, 4s, 4d, 5s
Correct Answer:
4s, 3d, 4p, 5s, 4d
Explanation:
The sub-shell with lowest value of (n + l) is filled up first. When two or more sub-shells have same (n + l) value the subshell with lowest value of ‘n’ is filled up first therefore the correct order is orbital 4s3d4p5s4d
