Question:

How many electrons in an atom may have the following quantum numbers?

(a) n = 4,

 

(b) n = 3, l = 0

Answer:

Total number of electrons in an atom for a value of n = 2n2

 

a) Total no of electrons when n=4 ,then n= 2x42 = 32 & half of them have ms = -1/2

 

b) When n= 3, l=0 means 3s orbital which can have 2 electrons .
