Answer;

NH3, because nitrogen forms a single bond with each hydrogen atom.

Explanation; Nitrogen and hydrogen are both non-metals. An atom of nitrogen has 5 electrons in its outer shell, while that of hydrogen has 1 electron in its outer shell. Three hydrogen atoms each share their 1 electron with nitrogen to form three covalent bonds and make an ammonia molecule (NH3) Therefore; NH3 has a covalent single bond among its nitrogen and hydrogen atoms. A covalent bond means the N and H atoms share valence electrons
