What type of bonds hold together the atoms in an oxygen molecule?

Covalent bond

Explanation:

Covalent bond:

"The bond which is formed by the sharing of electrons between the atoms is called covalent bond"

The covalent bond is less stronger than ionic bond so require less energy to break as compared to the energy require to break the ionic bond.

The covalent bond is present between the oxygen molecule. It is the bond which is formed by the sharing of electrons between the two atoms of oxygen. Oxygen is present in group six of periodic table so there are six valance electrons are present. Oxygen molecules is formed by sharing the two valance electrons by each oxygen atom, thus double covalent bond is present in oxygen molecules. This is represented as O=O and two lone pairs are still present on each oxygen atom.
