The N-Br bond is considered unstable primarily due to the significant difference in electronegativity between nitrogen and bromine. Nitrogen, being more electronegative, has a strong tendency to attract electrons, which creates a partial positive charge on bromine. This polarization weakens the bond, making it more susceptible to cleavage. Additionally, bromine's larger atomic size and lower bond dissociation energy contribute to the bond's instability, making it easier to break under various conditions.
Nitrogen and bromine form a covalent bond when they combine. In this bond, nitrogen typically shares three of its electrons with bromine, resulting in the formation of nitrogen tribromide (NBr₃). This compound features strong covalent interactions due to the sharing of electrons between the two elements, allowing for stable molecular formation.

Unstable isotopes are radioactive isotopes, can disintegrate and emit radiations.
Unstable.
Not all isotopes are unstable. But now more than 3 000 unstable isotopes are known, artificial or natural.
