How do I write an Ionic name of a coumpound?

Question

They have 2 different charges...how would i write it like that?

Ex: Ca(C2H3O2)2 +2, -1

Ca has a charge of +2 but C2H3O2 only has a charge of -1

Answer 1

In this example, write calcium acetate. Calcium has only a 2+ charge in compounds, so there is no confusion.

If the compounds were CuC2H3O2 and Cu(C2H3O2)2, you would write the first one either cuprous acetate or copper(I) acetate. The second is cupric acetate or copper(II) acetate.

The system with Roman numerals is the Stock system. Your teacher may tell you the system (s)he wants you to use.
