For CaCO3 (Calcium carbonate) we have an ionic compound and need to take that into account when we draw the Lewis Structure. We’ll first draw the metal and put it in brackets with its charge on the outside (video: finding ionic charge: [ Ссылка ]).

Next we'll draw the Lewis Structure for the CO3 2- ion (video: Lewis Structure for CO3 2-: [ Ссылка ]).

The Lewis structure of CaCO3 is also called Calcium carbonate.
