Question

Give the maximum number of electrons in an atom that can have these quantum numbers. (a) n = 4 (b) n = 2, 1 = 2 (c) n = 4, l = 0, m, = 0 (d) n = 3 (e) n = 2, l = 1, me = -1, ms = -1/2

Answer 1

(a)When n=4 the number of electrons are 2n^2=2*4^2= 32

(b) when n= 2 ,l= 2 then it is d orbital and the number of electrons are 10

(c) when n=4,l=0 then it is s orbital and for ml=0 then the number of electrons are 2.

(d) when n=3 the maximum number of electrons are 2n^2=2*3^2=18.

(e) when n=2,l=1,ml=-1,ms=-(1/2) it has only one electron.
