First I wanted to create something related to the alchemy like this:
But then decided it would be better to use real chemistry. So here are my themes and words:
metals (easy): rubidium, strontium, scandium, yttrium, molybdenum
nonmetals (medium): hydrogen, helium, krypton, nitrogen, chlorine
metalloids (hard): tellurium, silicon, germanium, arsenic, antimony
I think this might be even somewhat educational. I don’t know.
Hope you like the idea.
