    Is this a puzzle? They are all elements on the periodic table – but I am not sure they have anything in common other than that.

      Ok, so they are all different elements on the periodic table – I hope this isn’t a homework question *giggle*

      Argon is a gas, lutetium and erbium are both rare earth metals, while boron is more of a metalliod – it is often found as a mineral in the earth. And astatine is a radioactive halogen…

      Hope this helps!
