Question

What is the maximum number of electrons that M shell can accommodate? Give reasons for your answer.

Answer 1

Dear Student,

Maximum number of electrons that a shell (K, L, M and N.... ) can hold is given by is given by 2n² rule where n is the number of shell.
For K shell, n= 1 2$\times$1² = 2, means K shell can accommodate 2 electrons
For L shell, n = 2, 2$\times$ 2² = 8, means L shell can accommodate 8 electrons.
For M shell, n = 3, 2 x 3² = 18, means M shell can accommodate 18 electrons.
For N shell, n = 4, 2$\times$4² = 32, means N shell can accommodate 32 electrons.
