Difference between magnesium(II) nitrate and magnesium nitrate?
I am supposed to explain why saying magnesium(II) nitrate is incorrect when naming Mg(NO3)2, but even after reading the book an looking through all my notes, I still can't figure it out.
Could someone please shed some light on this for me? Those (II) things are really confusing. Perhaps you have something to share that would explain the positive charges in roman numerals (stock system, I believe it's called)?
I need to know by tomorrow morning. Thanks

magnesium nitrate is Mg(NO3)2 because Magnesium has a plus 1 charge and NO3 has a minus 1 charge, so the 2 from the magnesium goes to the Nitrate and the 1 from the NO3 goes to the Magnesium making 1 Mg and 2 NO3 (Mg(NO3)2). Magnesium (II) Nitrate doesnt exist because the parentheses are only for some of the transition metals that have more than 1 charge.
