Question

The total number of electrons that can be accommodated in all the orbitals having principal quantum number $2$ and azimuthal quantum number $1$ are

• A. 2
• B. 4
• C. 6
• D. 8

Answer 1

Answer: (C)

When $n=2$ and $l=1$, then subshell is $2p$.
The number of orbitals in p-subshell.
$=(2l+1)=(2\times 1+1)=3$
Total (maximum) number of electrons
$=2\times$number of orbitals
$=2\times 3=6$
(as each orbital contains $2$ electrons)
