* Covalent bonds occur when atoms share electrons to achieve a stable electron configuration. In the case of hydrogen peroxide, the hydrogen atoms each share one electron with the oxygen atom, and the oxygen atoms share one electron with each other.

Let's break it down:

* Hydrogen (H): Has one electron in its outermost shell and needs one more to become stable.

* Oxygen (O): Has six electrons in its outermost shell and needs two more to become stable.

The hydrogen atoms each form a single covalent bond with an oxygen atom, and the two oxygen atoms form a single covalent bond with each other. This results in the following structure:

H - O - O - H

Important note: While the primary bonding is covalent, hydrogen peroxide also exhibits hydrogen bonding between molecules. This is a weaker type of bond that occurs due to the attraction between the partially positive hydrogen atom of one molecule and the partially negative oxygen atom of another.
