Question

The number of orbitals in the shell in which the h-subshell first arises is:

• A. $10$
• B. $12$
• C. $25$
• D. $36$

Answer 1

The correct option is D $36$

For 'h' subshell, azimuthal quantum number '$l$' = 5.
We know that, $l$, ranges from $0$ to $n-1$ for a given principal quantum number '$n$'.
Hence, the minimum possible value of of $n$ to have ‘h' subshell is $n=l+1=5+1=6$
The number of orbital present $=6^2=36$
