The maximum number of electrons that can have principal quantum number

1.	The maximum number of electrons that can have principal quantum number, n = 3 and spin quantum number m_s= - 1//2 is ________.
Answer» Solution :Total NUMBER of electrons with (n=3) `=2n^2 =18` Out of these 18 electrons, 9 electrons will have anticlcokwise SPIN `(m_s = -1/2)`
