Electrons spin in shells around the nucleus. What is the maximum number of electrons that the closest shell (n = 1) can contain?

The symbol "n" represents the primary orbital where electrons are located. The sub shells are called s, p, d and f. When n = 1, the electron configuration is 1s2, this means that the maximum number of electrons that this shell contains is 2 electrons under the s-subshell

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

[tex] \huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}[/tex]

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

In First shell only 2 electron can be placed

[tex]2 {n}^{2} \\ n = 1 \: (bez \: \: number \: \: shell \: = 1) \\ so \\ 2 { n}^{2} = 2 \times {1}^{2} = 2 \: electrons[/tex]
