One Letter Periodic Table Symbols - Sudden Death

There is no way I got to 12 quite easily and then got stuck, thinking there were no more, guessed R, only to realise I’d forgotten about hydrogen. The only elements starting with h I could think of were holmium and hafnium somehow.

can I make a Spanish translation??

Hm tougher than anticipated, thought I would ace this.. suddenly my mind didn't want too cooperate ( it is early, but still)

I thought lithium was L

TUNGSTEN damn it

D and T are representations of isotopes of Hydrogen - Deuterium (D) and Tritium (T).

The question only asks for alphabets that are symbol for an element. Deuterium and Tritium are forms of elemental hydrogen.

If they are not to be accepted, the question should ask for primary isotopes of elements

Good quiz! I managed 13/14 (missed Y)

I thought radon was R lol
