Question

select the reasons why the molecule formed by two hydrogen atoms (h₂) is stable. it has no net charge. it is held together by a covalent bond. the octet rule is not satisfied. it is held together by an ionic bond. it has no unpaired electrons.

Explanation:

• A neutral molecule with no net charge is inherently more stable than charged species, so this applies to $\text{H}_2$.
• $\text{H}_2$ forms when two hydrogen atoms share a pair of electrons, which is a covalent bond, this bond stabilizes the molecule.
• Hydrogen follows the duet rule (2 valence electrons) instead of the octet rule; not satisfying the octet rule does not contribute to stability here.
• Ionic bonds form between atoms with large electronegativity differences, which does not apply to two identical hydrogen atoms.
• In $\text{H}_2$, the two shared electrons fill the 1s orbital, leaving no unpaired electrons, and species with no unpaired electrons are more stable.

Answer:

It has no net charge.
It is held together by a covalent bond.
It has no unpaired electrons.
