The maximum number of electrons that can be accommodated in M Shell of an atom are:
Correct answer: C. 18
- A. 8
- B. 32
- C. 18
- D. 25
Explanation
The maximum number of electron that can accommodate in a shell is given by the formula 2n2. For M shell n=3, hence M = 2(3)² so M = 2(9) = 18. So the M shell can have a maximum of 18 electrons thus, option C is correct.

About Electronic Configuration
Electronic configuration describes how electrons occupy shells, subshells and orbitals around an atom. Questions use the Aufbau principle, Pauli exclusion principle and Hund's rule to write configurations, identify valence electrons, form ions and explain periodic trends, including common exceptions such as chromium and copper.
