WebWhy is nitrogen very unreactive? Nitrogen exists as a diatomic molecule whereby 2 nitrogen atoms are joined by a triple bond (N≡N). The enthalpy of this bond is very high and hence requires a lot of energy to break. There isn’t a permanent dipole in the molecule … WebPlatinum is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Platinum is one of the least reactive metals. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal.
