If K and L shells of an atom are full, then what would be the total number of electrons in the atom?

Text Solution

Verified by Experts

K shell becomes full with 2 electrons and L shell becomes full with 8 electrons. So, if the K and L shells of an atom are full, then it will have a total of `2 + 8 = 10` electrons in it.
