- <em>Bromine</em>
- <em>Phosphorus</em>
- <em>Strontium</em>
Most similar to nitrogen
N and H form the compound NH₃. P is a nonmetal in the same group as N in the Periodic Table (Group 15) so it has similar chemical properties. In fact, P and H form the compound PH₃, a non-metallic hydride as NH₃.
Least similar to nitrogen
Sr is a metal, which is in the Group 2 in the Periodic Table (alkaline earth metal), so it is very different from N, and it forms a metallic hydride SrH₂.
