Hydrogen is my all around favorite.

>responsible for energy generation in biochemistry (pic related, ATPase molecular motor is driven by proton gradient and sequential protonations)
>acid-base chemistry
>highly explosive diatom in presence of oxygen
>can exist as five phases of matter, including metallic
>studying hydrogen gave rise to molecular orbital theory and quantum theory
>has a cool looking, beta-emitting radioisotope: tritium


I also love pretty much all of the platinum group metals.

ATP synthase, also kinesin, dynein, actin and myosin in muscle, I think molecular motors are amazing
