Answered by sunayana4

HEYAAAA...

Generally, 8 valence electrons are needed for an atom to be stable..

Except hydrogen and helium....they requires 2 Valence electrons....

HOPE THIS HELPS

dragon12: you have comment something on my answer.....

sunayana4: yaa....valence shell can only have 8 electrons in it

dragon12: But some noble gases have 18 electron in thier valence shell....But they are also stable....

sunayana4: its a rule that outermost shell can contain only 8 electrond

dragon12: Ya you are right........

dragon12: I have checked.....

Answered by dragon12

Some elements like hydrogen and helium requires 2 -e in outermost shell to become stable because they complete thier duplite...

But other elements requires 8, -e in thier valence shell to become stable...because they complete their duplete
