Question

how can hydrogen gas be stable all though two electrons are needed
in the first shell but but according to the octet rule we need 8
electrons for the atom to be stble

Dear student,

There is an exception to the octet rule that the maximum electrons
that can be filled in first shell is 2

Hence hydrogen gas H2 is stable by sharing their single electrons
with each other and be stable with two electrons in the first
shell
