The maximum number of electrons in a subshell is given by the expression
A.
$$4l - 2$$
B.
$$4l + 2$$
C.
$$2l + 2$$
D.
$$2{n^2}$$
Answer :
$$4l + 2$$
Solution :
The number of orbitals in a subshell $$ = \left( {2l + 1} \right)$$
where, $$l$$ = azimuthal quantum number
Since, each orbital contains maximum two electrons, the number of electrons in any subshell
$$\eqalign{
& = 2 \times {\text{number of orbitals}} \cr
& = 2\left( {2l + 1} \right) \cr
& = 4l + 2 \cr} $$
