Question

What is the total number of orbitals in the shell to which the $g$-subshell first arise?

• A. $9$
• B. $16$
• C. $25$
• D. $36$

Answer 1

The correct option is C $25$

For g subshell $l=4$

Minimum n for g subshell to exist $=l+1=5$

The number of orbitals in a shell with $(n=5)$ is $=n^2=5^2=25$

Where, $n=$ the principal quantum number.

There will be 25 orbitals in the shell in which the g subshell will arise first.
