Maximum number of electrons in a subshell with l=3 and n=4 is

Options

  1. A14
  2. B16
  3. C10
  4. D12

Correct answer

A. 14

Step-by-step solution

n represents the main energy level and l represents the subshell. If n=4 and l=3 , the subshell is 4 f . In f subshell, there are 7 orbitals and each orbital can accommodate a maximum of two electrons, so, maximum number of electrons in 4 aligned 4 f subshell & =7 2 & =14 aligned
