Why is H2 stable even though it never satisfies the octet rule?

1.	Why is H2 stable even though it never satisfies the octet rule?
Answer» The valence shell configuration of hydrogen atom is 1s¹. Two hydrogen atoms approach each other and share their valence electrons. By having two electrons in its valence shell, H atom attains the nearest noble gas configuration of He. H₂ molecule attains stability due to duplet formation. Hence, H₂ is stable even though it never satisfies the octet rule.

Answer»

The valence shell configuration of hydrogen atom is 1s¹.

Two hydrogen atoms approach each other and share their valence electrons.

By having two electrons in its valence shell,

H atom attains the nearest noble gas configuration of He.

H₂ molecule attains stability due to duplet formation.

Hence,

H₂ is stable even though it never satisfies the octet rule.
