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".
