I was pretty sure an electron wasn't a negatively charged atom, but a negatively charged "part" of an atom, as a counterpart of protons which are positively charged. As said in the second question, a charged atom is an ion, so a negatively charged atom should be an anion.

I think

Kool. Learned some stuff as well. I think you can remove the requirement to write "degrees" from the boiling answer, though.

Yes please. I knew it was 100 but couldn't figure out why it wasn't being accepted.

Nice Job. The Only thing I'd suggest is to change Avogadro's number to 6.022x10^23, because most chemists I know use 6.022, instead of 6.02

I would suggest you swap the question with the answer. Make 6.022×1023 the hint and "Avogadro's number" the answer.

As the number can be interpreted in different ways by different people, it would be quite difficult.

Should accept "Cellular Respiration" for the opposite of photosynthesis question

I guess the first lanthanide is cerium and lanthanum is part of the d block element.

I knew 4 answers in my first language that I couldnt translate to english... Could you add some type-ins, especially for chlorophyll?
