What Determines Whether a Covalent Bond Forms? Covalent bonds form when two nonmetallic atoms have the same or similar electronegativity values. So, if two identical nonmetals (e.g., two hydrogen atoms) bond together, they will form a pure covalent bond. When two dissimilar nonmetals form bonds (e.g., hydrogen and oxygen), they will form a covalent bond, but the electrons will spend more time closer to one type of atom than the other, producing a polar covalent bond. 1  Article. 2  Article. 3  Article. 4  Article. 5  Article. 6  Article. 7  Article. 8  Article.
