OPTION (a)

[tex]2 {n}^{2} [/tex]

[tex] \bold { \red{ \star{ \blue{EXAMPLES}}}}[/tex]

In First shell only 2 electron can be placed .

[tex]2 {n}^{2} \\ n = 1 \: (bez \: \: no \: \: shell \: = 1) \\ so \\ 2 { n}^{2} = 2 \times {1}^{2} = 2 \: electrons[/tex]

In second shell 8 electrons can be placed

[tex]2 {n}^{2} \\ n = 1(bez \: \: no\: \: shell \: = 2) \\ 2 {n}^{2} = 2 \times {2}^{2} = 2 \times 4 = 8 \: electrons[/tex]
