Correct Answer: 18
Solution : The correct option is 18.
The maximum number of electrons that the M shell can hold is determined by the formula 2n2, where "n" is the principal quantum number of the shell. For the M shell, which is the third shell, n is equal to 3. Therefore, the maximum number of electrons in the M shell is:
2 * (3)2 = 2 * 9 = 18.
So, the M shell can hold a maximum of 18 electrons.
