Question

Identify the subshell in which electrons with the following quantum numbers are found :
1. n = 4, l = 2
2. n = 6, l = 0

• A. 4p, 6s respectively
• B. 4d, 6p respectively
• C. 6s, 4p respectively
• D. 4d, 6s respectively

Answer 1

The correct option is D 4d, 6s respectively

1. n = 4, l = 2
Given quantum numbers are:
Priniciple quantum number; n = 4 mean 4th shell
Azimuthal quantum number; l = 2 mean d-subshell
So, 4d is the subhell.

2. n = 6, l = 0
Given, quantum numbers are:
Priniciple quantum number; n = 6 mean $6^{th}$ shell
Azimuthal quantum number; l = 0 mean s-subshell
So, 6s is the subhell.
Hence the correct option is (d).
