	First one to take the quiz! Score was abyssmal especially since I took a chemistry paper at the start of this year.

	Good quiz idea but I think the diatomic clues are too vague - maybe you could give the atomic number as well? Or leave those out as they're not technically ions?

	Maybe accept CH3COO- for acetate

	I agree with the two previous comments. I was very confused by the diatomic clues because (a) there were 7 of them with nothing to distinguish one from the others and (b) they're not ions. Also, for many of these the formatting is off (e.g. Ammonium should be NH4 + not NH 4+, the chlorine-oxygen ions should be ClO# - not ClO #-, etc.)

	Technically, the diatomic stuff are molecules, not ions... ..or if you really want to include them, you can do it the other way round: give the formula (Cl2) and ask for the name (Chlorine).

	over my head!

	Good quiz, though I dispute the suggestion that caesium is a common ion! :-) Zinc also has ions Zn+. Also, I think you ought to include some more complex ions. Sulphates, carbonates and so on are all very common. (It looks like you maybe used to have some of those but removed them?)
