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 ...

**8th grade physical science**

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?

**8th grade physical science**

it depends....is the carbon giving an electron or taking one?

**Math**

im pretty sure anyway
