    It will be a metal, as gases have negative charges. Na has 1+ Cu has 2+/1+ K has 1+ Fe how ever has 3+/2+ Mg has 2+ So your answer is?

    You can also look at your compound and tell right away which one it is, as Cl has a charge of 1-, and you have to balance compounds as well.

    so it would be Cucl?

    Fe has a 3+ ion and a 2+ ion

    so this may be a stupid question but what Cl3 stand for?

    Mhm ok, so it seems you've not learned how to "balance" the compounds, notice how in the periodic table I've put a 1- charge on the right side, and Cl falls into it right?

    |dw:1435957604642:dw| you want to balance it out when you make a compound so they both have equal charged

    so you have iron(iii)chloride now

    but would it that mean that it would be 2+ because the 3+ and the -1? maybe i am over thinking it

    You want to have a neutral charge, or let me simplify it more, you want the "elements" to have equal charges in the compound

    So let me ask you one question, how would you make a compound of lets say magnesium nitride

    Look at the periodic table for charges

    it would be 2+ right

    Well, you have |dw:1435957943479:dw| you can ignore that 2 for now it just means it's a diatomic element, but balance this compound

    so like MG,N-3?i know that its like if you have two that are the same its just the letters

    No, notice how magnesium has a 2+ charge, and nitrogen has a 3- charge, we are looking for magnesium nitride, which would then be \[\huge Mg_3N_2\] easy as that

    You need to learn this before you can balance a chemical equation
