Witryna21 sie 2024 · Nitrogen is often thought of as being fairly unreactive, and yet all these metals combine with it to produce nitrides, X 3 N 2, containing X 2 + and N 3-ions. Nitrogen is fairly unreactive because of the very large amount of energy is required to break the triple bond joining the two atoms in the nitrogen molecule, N 2 .
