Maximum number of electrons in a subshell with I = 3 and n = 4 is:
Correct answer: A. 14
- A. 14
- B. 16
- C. 10
- D. 12
Explanation
The maximum number of electrons in a subshell is calculated using the formula 2(2l + 1), where l is the azimuthal quantum number. For a subshell where l = 3 (which corresponds to the 'f' subshell), the maximum number of electrons is 2(2(3) + 1) = 2(7) = 14. This is why Option A is correct. Other options do not match this calculation: 16, 10, and 12 are incorrect as they do not satisfy the formula for the given l value.

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.
