Answer

Brief Explanations:

The octet rule states that atoms tend to gain, lose, or share electrons to have eight electrons in their valence shell for stability. However, hydrogen has only one electron - shell (the first shell), which can hold a maximum of 2 electrons. So, it forms covalent bonds to achieve a full valence shell of 2 electrons.

Answer:

Hydrogen’s valence shell can hold only up to two electrons.
