Recall that hydrogen has 1 electron in its outer shell and needs 2 electrons to complete its valence shell, following the duet rule.
Understand that in covalent bonding, atoms share electrons to achieve a full valence shell.
Since hydrogen needs only one more electron to complete its valence shell, it can form a single covalent bond by sharing one pair of electrons with another atom.
Recognize that forming more than one bond would exceed hydrogen's capacity because it only has one electron to share and can only accommodate two electrons total.
Therefore, hydrogen can form exactly one single covalent bond to satisfy its valence electron requirement.
