Question

Cl- ion has completely filled k, l and m shells. Explain.

Answer 1

Answer:

as Cl- is an ion of chlorine

therefore Cl- has 17+1 = 18 electrons

as K shell can hold 2 electrons

L shell can hold 8 electrons

and M shell can hold 18 electrons

but M as last shell can only hold 8 electrons

Total no. of electrons K , L and M shells can hold is 18 electrons

Also Cl- has 18 electrons

from this we can say that

Cl- ion has completely filled K , L and M shells
