Sorry James,
Nitrogen is not a noble gas, but in its diatomic form of N2 it is nearly as unreactive as the noble gases and hence does exhibit some of the properties of noble gases. He, Ne, Ar and others are the noble gases. Sorry, I'm a maths and science teacher! Chris james wade writes: > That makes sense... Nitrogen is a noble gas right?
