what is the charge on carbonate ion? Compared to the number of protons, how many electrons does the carbonate ion have?
it depends....is the carbon giving an electron or taking one?
it doesn't say
hmmm...you would have the same # of protons and electrons in its normal state, but an ion- the element gives up an ion and another element takes that ion...what is carbonate...carbon and what?
carbonate:
A salt or ester of carbonic acid, containing the group CO3. The reaction of carbonic acid with a metal results in a salt (such as sodium carbonate), and the reaction of carbonic acid with an organic compound results in an ester (such as diethyl carbonate).
carbonate:
Any other compound containing the group CO3. Carbonates include minerals such as calcite and aragonite.
so CO3 would be that carbon has 6 electrons and oxygen has 8
meaning that c has 4 electrons in the outer shell and o has 6. they don't make an even 8 so idk how they make and ion because they like to have a full outer shell and those combining wouldnt do that. so imnot sure how to answer that...sorry
