Question

Correct increasing order of energy of subshell for 5th
period :-
(1) 5s, 4f, 4d, 5p (2) 5s, 5p, 5d, 5f
(3) 5s, 4d, 5p
(4) 5s, 4p, 5p
plz explain...​

Answer 1

Answer:

• 2- 5s,5p,5d,5f
• According to moellar chart
• The filling order of atomic orbitals

Answer 2

Answer:

it will be 3rd option

Explanation:

according to afbau rule subshells are filled in increasing order of their energy or (n+l) rule.

so order of filling electrons is

1s,2s,2p,3s,3p,4s,3d,4p,5s,4d,5p and so on

i hope you can understand
