Ion Quick Quiz for bonus

For the first thirty questions, answer with just the formula, for the next thirty, answer with just the charge.

Example: For 1-30, if the question asks: "calcium ion =" You should answer: "Ca" (Don't forget - uppercase "C" lower case "a.") If the question asks: "nitrate ion =" you should answer "NO3" (No need to make the 3 a subscript as in NO₃).

For questions 31-60, if the question asks: "Ca^? =" it is asking for the charge on the Ca ion and you should choose "2+" from the drop down menu, and if the question asks: "NO₃^? =" it is asking for the charge on the NO₃ ion and you should choose "1-"

If you really know these ions, four minutes is plenty of time.
