The anion carbonate is (CO3)2-.
The symbol equation for Potassium Carbonate is...K2CO3:)
Copper(II) Carbonate (or Cupric Carbonate) is made up of Copper ions, and Carbonate ions. The coppers have a +2 charge, and carbonate has a -2 charge. The formula is Cu(II)CO3
The chemical equation for zinc carbonate is ZnCO3
Iron(III) carbonate or ferric carbonate.
CaCO3
The symbol equation for Potassium Carbonate is...K2CO3:)
The chemical symbol for sodium carbonate is Na2CO3.
Hydrogen carbonate is a compound, not an element, and it therefore has a formula, not a symbol: H2CO3.
The formula and charge for the carbonate ion is CO32- and the formula and charge of the magnesium ion is Mg2+. Together they make magnesium carbonate, MgCO3.
the symbol for calcium carbonate is Caco
The are 24 valence electrons in a carbonate ion. http://www.800mainstreet.com/5/0005-006b-lewis.html
No carbonate has a negative charge so it is an anion.
The letter "C" is the symbol for carbon.
