Great quiz, original idea and challenging but not overly! Only issue is the 'C' answers. The current answer has 7 letters compared to some that are shown already like copper, which has 6. In addition, there's a missing 6 letter answer (Carbon).
Also, why are 4 of them already shown? For O, P, and S, you have to type all elements typing, but for C you don't...
I would second that, and add ‘Cesium’ (spelt Caesium here in the UK but always the six letter way on JP). I was baffled when it showed Calcium as my missing answer! Lol 😂
