In summary, the formula for magnesium nitrate is Mg(NO3)2, with the cation Mg+2 and two anions of nitrate (NO3) combining to form a neutral compound. The charges of -6 from the two oxygen atoms and -1 from the nitrate anion add up to -7, which is balanced out by the +2 charge of the magnesium ion. The subscript 2 indicates the presence of two nitrate anions in the compound.

Homework Statement



Write the formula for magnesium nitrate.

2. The attempt at a solution

Okay, so I get that I have to list the cation first and then the anion. I also understand that I have to take the charges into consideration and end up with a neutral compound. My question is why is the formula for magnesium nitrate

Mg(NO3)2

If Mg+2 N-3 and O[tex]^{3}_{-2}[/tex] to me it seems that O would have a total charge of -6 add the N charge and that's -9 while Mg has just +2. So this doesn't seem to equal out, plus I don't understand where the subscript 2 is from.

Thanks for the help sorry if this is a simple question.

NITRATE has a charge of negative one;
Nitrate has a charge of -1.

Yes the oxygens each have associated charge of -2 each.

One Mg ion has charge +2, so it needs 2 nitrates.

Oh :blushing: thanks!

Could we put in a chart or a table in a message? Someone could clarify things like charge accounting for an ion very nicely using a table. I see no tags for creating a chart or table.
