Text Solution

Verified by Experts

The correct Answer is:
A
(a) n represents the main energy level and l represents the subshell.
If n=4 and l=3, the subshell is 4f.
In f-subshell, there are 7 orbitals and each orbital can accommodate a maximum number of two electron, so maximum number of electrons in 4f subshell `=7xx2=14`.
