* Electronegativity: Nitrogen (N) has an electronegativity of 3.04, while bromine (Br) has an electronegativity of 2.96. The difference in electronegativity is relatively small, meaning neither atom has a strong enough pull to completely take an electron from the other.

* Sharing Electrons: Since neither atom is likely to fully donate an electron, they will instead share electrons to achieve a stable octet (8 electrons in their outer shell).

* Formation of a molecule: The sharing of electrons results in the formation of a covalent bond, and the resulting molecule is called nitrogen tribromide (NBr₃).
