Question

the total number of maximum electrons that can be accommodated in any d-sublevel from all the degenerate orbitals together in that level is ____ and in any f-sublevel is ____.

1. 5, 7
2. 10, 14
3. 20, 32
4. 2, 2

Explanation:

Step1: Recall electron subshell rules

A d - sublevel has 5 degenerate orbitals, and each orbital can hold a maximum of 2 electrons. So the maximum number of electrons in a d - sublevel is \(5\times2 = 10\).

Step2: Recall f - sublevel rules

An f - sublevel has 7 degenerate orbitals, and each orbital can hold a maximum of 2 electrons. So the maximum number of electrons in an f - sublevel is \(7\times2=14\).

Step3: Match with options

From the above calculations, the number of electrons in d - sublevel is 10 and in f - sublevel is 14, which matches option 2.

Answer:

1. 10, 14
