Question

Given,(A) (B) n=3,1=2, m1=-1, ms=+12 The maximum number of electron(s) in an atom that can have the quantum numbers as given in and (B) respectively are:

Accepted Answer

A) $n = 5$$$l = 0\ {	ext{ }m}_{l} = 0 $$$l = 1\ {	ext{ }m}_{l} = \mathbf{- 1},0,1 \Rightarrow 2$ electrons$l = 2\ {	ext{ }m}_{l} = - 2, - \mathbf{1},0,1,2 \Rightarrow 2$ electrons$l = 3\ {	ext{ }m}_{l} = - 3, - 2, - \mathbf{1},0,1,2,3 \Rightarrow 2$ electrons$l = 4\ {	ext{ }m}_{l} = - 4, - 3, - 2, - \mathbf{1},0,1,2,3,4 \Rightarrow 2$ electronsTotal number of electrons $= 8$B) $n = 3,l = 2,{	ext{ }m}_{l} = - 1,{	ext{ }m}_{s} = + 1/2 \Rightarrow$ only 1 electron is possible
