-1
BeSO4 Sulfate is a polyatomic ion = SO4 and this has a charge of -2 and Beryllium usually has a charge of +2
The chemical formula of zinc diiodide is ZnI2.
The subscript of the second ion identifies the oxidation state of the transition metal
If you break down the chemical by it's elements and apply some simple rules, you can find the formula for a chemical compound.
-1
Potassium has a formal charge of +1, and sulfide has a formal charge of -2, so: K2S
The chemical formula for peroxide is O2 and the charge is 2-
the chemical formula of zinc sulphate is ZnSO4.
The chemical formula of carbonate anion is (CO3)2-.The chemical formula of magnesium cation is Mg2+.
BeSO4 Sulfate is a polyatomic ion = SO4 and this has a charge of -2 and Beryllium usually has a charge of +2
CrO4-2
== 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
SO4 with a minus 2 charge(-2)
Formula: XF3 where X is the element with which fluorine is bonded
The salt lithium chloride is LiCl. It's an Li+ ion and a Cl- ion.
The chemical formula of zinc diiodide is ZnI2.
