Question

Valency of an atom who have complete outermost ring

Answer 1

heya....!!!

✔here is ua answer:

___________________________________________❤

An atom can have a maximum of 8 electrons in its outermost orbit. The presence of 8 electrons in theoutermost shell indicates stability of an atom. An atom tends to lose electron if it has one to four electrons in its outermost orbit. When an atomdonates these free electrons it has positive valency.

hope it helps...!!!❤

Answer 2

Here is ur answer!!!
Outermost shell consists of 8 electrons. As their outermost shell is completed they r also known as noble gas elements it also symbolizes stability of the atom.... Valency of an atom who have complete outermost shell is 0 since there is no place for any extra electrons.....
