Question

How Many $\mathrm{p}$ Orbitals Can Be Filled In A Shell?

Answer 1

The number of p orbitals filled in a shell are:

For $\mathrm{p}$orbital:

1. principal quantum number($\mathrm{n}$) $=2$
2. angular quantum number($\mathrm{l}$) $$\begin{gathered} =\mathrm{n}-1 \\ =2-1 \\ =1 \end{gathered}$$
3. magnetic quantum number($\mathrm{m}$) $=-\mathrm{l}$ to $+\mathrm{l}$

$=-1,0,+1$

Thus, Three $\mathrm{p}$ orbitals can be filled in a shell.
