The maximum number of electrons that can be present in an shell is

$\orange{\underline{\huge{\bold{\textit{\green{\bf{OPTIONS}}}}}}}$

a) $2 {n}^{2}$

b) $2 {n}^{2} + 1$

c) 2n

d) none of these.

$\huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}$

OPTION (a)

$2 {n}^{2}$

$\bold { \red{ \star{ \blue{EXAMPLES}}}}$

In First shell only 2 electron can be placed .

$2 {n}^{2} \\ n = 1 \: (bez \: \: no \: \: shell \: = 1) \\ so \\ 2 { n}^{2} = 2 \times {1}^{2} = 2 \: electrons$

In second shell 8 electrons can be placed

$2 {n}^{2} \\ n = 1(bez \: \: no\: \: shell \: = 2) \\ 2 {n}^{2} = 2 \times {2}^{2} = 2 \times 4 = 8 \: electrons$
