Covalent Bonds: A Hydrogen Example. A covalent bond is a chemical bond that comes from the sharing of one or more electron pairs between two atoms. Hydrogen is an example of an extremely simple covalent compound. A hydrogen example.
A covalent bond is formed when two atoms share electrons for stability, as seen in examples like hydrogen gas (H₂) and water (H₂O). In H₂, two hydrogen atoms share their electrons, while in H₂O, one oxygen atom shares electrons with two hydrogen atoms. These bonds are essential for forming many chemical compounds.
