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

The maximum number of electrons that can occupy K and L-shells of an atom are 2 and 8 respectively. Therefore, if K and L-shells of an atom are full, then the total number of electrons in the atom would be (2 + 8) = 10 electrons.

2 electrons are there in K shell.
8 electrons are there in L shell.
∴ Total No. of Electrons = 2 + 8 = 10

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.

The maximum number of electrons that can occupy K and L-shells of an atom are 2 and 8 respectively. Therefore, if K and L-shells of an atom are full, then the total number of electrons in the atom would be (2 + 8) = 10 electrons.
