Is O2 covalent or ionic bond?

Answer 1

It is covalent.

Ionic bonds only form between two different elements with a larger difference in electronegativity. O2 contains two atoms of the same element, so there is no difference in electronegativity.

Answer 2

Oxygen can form both ionic and covalent bonds

Answer 3

Oxygen molecule is O2 which is covalently bonded.

Oxygen can form covalent bonds e.g in water H2O and the ion O2- in metal oxides such as Na2O

Answer 4

Oxygen gas or O2, since it is two atoms of a non-metal in a molecule would be considered a covalent bond, the term ionic bond usually refers to the bond between a non-metal and a metal.

Answer 5

yes it is
