The maximum number of electrons in an atom with n=3 and l=2 is:
Correct answer: A. 10
- A. 10
- B. 6
- C. 18
- D. 0
Explanation
In this case l = 2then m = −2,−1,0,+1,+2so there are 5 orbitals and each orbital contain 2 electronsSo for value n = 3 and l= 2 there are 10 electrons.The maximum number of electrons in a subshell with l=2 and n=3 is 10.
This question appeared on the NUMS 2015 paper, which you can sit online with every answer explained.

About Quantum Numbers
Quantum numbers describe an electron's energy level, subshell, orbital orientation and spin. You examine the principal, azimuthal, magnetic and spin quantum numbers, their allowed values, orbital capacity and how they determine electronic configurations and distinguish electrons within an atom.
