Question

The maximum number of electrons in 2nd shell.

Answer 1

Given:

Second shell i.e. $\mathrm{n}=2$

Formula used:

Maximum number of electrons$=2{\mathrm{n}}^2$ …… (Here, $\mathrm{n}$ is the number of the shell)

Calculate the maximum number of electrons in 2nd shell:

Maximum number of electrons$=2{\mathrm{n}}^2$

Substitute $\mathrm{n}=2$. Thus,

Maximum number of electrons$=2\times 2^2$

Maximum number of electrons$=8$

Thus, the maximum number of electrons in 2nd shell is $8$.
