Name the charges (+1, -1, etc.) for ions of certain groups and a few transition elements/ elements with multiple possible charges.
Because JetPunk does not allow for + and - symbols to be necessary in answers, they are not required when your enter your answer. However, it is still important to know whether the charge is + or -.
For ions with multiple charges, you may type of an answer such as "+1 or +2," for example, however, you may simply put "1 2" or "12" if you wish.
Also note that just because some elements have multiple charges, it does not mean that ALL elements have multiple charges. Many only have 1 possible charge, and as such it is only necessary to input one number for some answers.
