Question
If K and L shells of an atom are full, then what would be the total number of electrons in the atom?
Advertisements
Solution
The maximum number of electrons present in a shell = 2n2
where n = shell number
Value of n for K shell = 1
∴ Maximum number of electrons in K shell = 2n2
= 2(1)2
= 2
Value of n for L shell = 2
∴ Maximum number of electrons in L shell = 2(2)2
= 8
Thus, total no. of electrons = 2 + 8
= 10
