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

1 Answer

Apr 21, 2018

3 subshells in 3rd shell and 25 orbitals in 5th shell.

Explanation:

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