The correct answer is 18.<\/section>\n
The maximum number of electrons that can be accommodated in an electron shell is given by the formula 2n\u00b2, where ‘n’ is the principal quantum number of the shell.<\/section>\n
Electron shells are denoted by K, L, M, N, … corresponding to principal quantum numbers n = 1, 2, 3, 4, … respectively. For the M shell, n=3. Therefore, the maximum number of electrons in the M shell is 2 * (3)\u00b2 = 2 * 9 = 18.<\/section>\n","protected":false},"excerpt":{"rendered":"
