No. A nitrate anion has a 1- charge.
== Since Nickel(III) has a +3 charge and Nitrate (NO3) has a -1 charge, the chemical formula for nickel(III) nitrate would therefore be Ni(NO3)3
Iron II nitrate contains an iron ion with a 2+ charge and has the formula Fe(NO3)2. Iron III nitrate contains an iron ion with a 3+ charge and has the formula Fe(NO3)3
Nitrate has a single, negative charge - NO3-
nitrate ion is: NO3- , so it has a -1 charge
-1 charge
-1 charge
H+1 and NO3-1 produce nitric acid. The two charges cancel so the compound has a net charge of 0.
NO3 with a negative 1 charge (and the 3 is the number of oxygen)
The formula and charge of the nitrate ion is NO3-, and the formula and charge of the magnesium ion is Mg2+. Together they make magnesium nitrate, Mg(NO3)2.
The NO3 polyatomic anion has a charge of 1-. Writing (NO3)3 means there are 3 such anions, each with a 1- charge, or a total charge of 3-. An example of this might be in the compound aluminum nitrate, Al(NO3)3.
Ammonium NH4 has a charge of +1 and nitrate NO3 has a charge of -1
Mg(NO3)2 is called magnesium nitrate. You do not use the prefix di for the nitrate since this is an ionic compound, and it can only be (NO3)2 as nitrate has a -1 charge and Mg has a +2 charge.
