The quantum numbers n , l , m , m_s respectively of the electron 3d^1

1.	The quantum numbers n , l , m , m_s respectively of the electron 3d^1 are
Answer» `sum_(l=0)^(l=n) 2(2l+1)` `sum_(l=1)^(l=n) 2(2l+1)` `sum_(l=0)^(l=n) (2l+1)` `sum_(l=0)^(l=n-1) 2(2l+1)` SOLUTION :Total NUMBER of electrons in any ENERGY level `E_(l=0)^(l=n-1) 2(2l+1)`
