# How many subshells are in the n = 3 shell? And How many orbitals are in the n = 5 shell?

• Number of subshells in $\text{n"^"th}$ shell $\text{= n}$
So, there are $3$ subshells ($\text{s, p, d}$) in $\text{3"^"rd}$ shell.
• Number of orbitals in $\text{n"^"th}$ shell ${\text{= n}}^{2}$
So, there are $25$ orbitals in $\text{5"^"th}$ shell.
