Here's why:

* Electronegativity: Nitrogen is more electronegative than hydrogen, meaning it has a stronger pull on shared electrons.

* Sharing of Electrons: Both hydrogen and nitrogen need to gain electrons to achieve a stable electron configuration. They achieve this by sharing electrons, forming a covalent bond.

Examples:

* Ammonia (NH3): This molecule contains three hydrogen atoms covalently bonded to a nitrogen atom.

* Amides (R-CONH2): These organic compounds contain a nitrogen atom bonded to a carbon atom and two hydrogen atoms.
