This group has all three different categories of metals: metals, non-metals, metalloids

One method used to isolate pure N2: combine and then distill it from a liquefied oxygen. Liquid nitrogen distills off first because it has a lower boiling point than liquid oxygen.

The Haber process is used to make ammonia by combining hydrogen and nitrogen.

Fe

Reaction for the Haber process: N2 (g) + 3H2 (g) ⇔ 2NH3 (g)

N2 is extremely stable because it has a triple bond.
