The charge on a carbonate ion is -2; therefore, the ion has two more electrons than protons.

There are two pairs of nonbonding electrons in a carbonate ion, CO32-. Each oxygen atom has two lone pairs of electrons, while the carbon atom does not have any nonbonding electrons in the ion.
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
how many protons does the carbonate ion have?
A carbonate ion (CO3^2-) has a total of 24 electrons. This is calculated by adding the number of electrons in a carbon atom (6 electrons per carbon atom) to the number of electrons in three oxygen atoms (8 electrons per oxygen atom).

how many protons does the carbonate ion have?
The are 24 valence electrons in a carbonate ion. http://www.800mainstreet.com/5/0005-006b-lewis.html
Iron carbonate is considered an ionic compound because it is made up of a metal (iron) and a polyatomic ion (carbonate). In this case, the iron atom donates electrons to the carbonate ion, resulting in the formation of an ionic bond.
Carbonate ions are double negatively charged (2-)CO32-
The carbonate ion, CO3 2-, has a total of 24 valence electrons. This is because there are three oxygen atoms, each contributing 6 valence electrons, and a charge of 2- indicates the addition of 2 electrons to account for the overall charge on the ion.
