What is the maximum numbers of electrons that can be associated with the following set of quantum numbers? n=3, l=1 and m=-1

Options

  1. A10
  2. B6
  3. C4
  4. D2

Correct answer

D. 2

Step-by-step solution

The orbital of the electron having n=3 , l=1 and m=-1 is 3 p_z (as m_m ) and an orbital can have a maximum of two electrons with opposite spins. 3 p_z arbital contains only two electrons or only 2 electrons are associated with n=3 , l=1, m=-1 .
