Why can a hydrogen atom form a covalent bond without fulfilling the octet rule?

The answer is: Hydrogen's valence shell can hold only up to two electrons.

Hydrogen (symbol: H) is a chemical element with atomic number 1, which means it has one proton and one electron.

Electron configuration of hydrogen atom: ₁H 1s¹.

In s orbital maximum number of electrons is two.

Hydrogen form bonds with electrons as closest noble gas helium (He).
