Question

What is the maximum number of electrons that can be accommodated in K-shell?

Answer 1

• The maximum number of electrons that can be accommodated in any shell is $2n^2$ (where $n$ is the shell number).

• The number of shells in K-shell is $1$.

• So the maximum number of electrons that can be accommodated in K-shell is:
  $=2n^2=2x{1}^2=2$
  
  Therefore, the maximum number of electrons that can be accommodated in K-shell is $2$.
