Question

if k and L shells of an atom are full then what would be the total number of electrons in the atom ? what is the valency of this element ?​

Answer 1

Explanation:

The maximum number of electrons that can be occupied in 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

Answer 2

electrons is 10

valency is 0

Explanation:

because in a k shell is 2 electrons

and l shell is 8

so, electrons is 10

valency is 0 because its l shell is complete
