Question

Diatomic molecules of gases are due to ___ bonds.

Answer 1

Answer: covalent.

Explanation:

• The difference in electronegativity between atoms in the molecule indicates the type of bond between the molecules.

• If the difference between the electronegativity from 0 to 0.4, this means that the bond is non-polar covalent bond.

• In a diatomic molecules, the molecule has atoms of the same type, so the difference in electronegativity between the atoms is zero.

• Thus, the bond in a diatomic molecule is covalent bond.

• For example, H₂, O₂, Cl₂, ...etc.
