I have only ever seen the spelling "cesium" I've never seen it spelled "caesium" so I figured it was a wrong answer and tried desperately to find another element in the remaining pool that I knew weren't elements... eventually I figured it out but took a while
It was the toughest one for me too, well the only one really, I was cruising along until there was still one left.. hmm which is it. Luckily I knew most of the others weren't it but wasn't totally sure about galactium, but lutetium made more sense. But if you had asked me a single question, is lutetium an element, I would have had to answer, not sure, no idea.
I absolutely abhor the way British "people" spell things, there isn't any reason to have an 'a' in Cesium. And no, it's not pronounced "Say-zee-um", it's pronounced "See-zee-um".
Watch me fumble the race at 98.5
Edit: now we both have 6 stars
I made this quiz like 5 months ago lol
Edit: I wrote that before I even played the quiz. I suck at this and I got only 9. Still congrats, though.
