Helium - Because it is the only inert gas? I think???

[gen2]

Radium is the odd one out
Hydrogen, Helium, Lithium and Beryllium are the first four elements in the periodic table. The fifth one is Boron.

Also, Radium is the only one which is radio active

[gen2]

You could also claim that Hydrogen is the odd one out because it is the only one with no neutrons in its nucleus
