Calcium carbonate (CaCO3) has ionic bonding between calcium ion Ca2+ and a polyatomic ion, CO2−3, but within the carbonate ion (CO32-), the carbon and oxygen atoms are connected by covalent bonds (shown above).

What type of compound is CaCO3?

Calcium carbonate is a chemical compound with the formula CaCO3 formed by three main elements: carbon, oxygen, and calcium.

Is CaCO3 ionic polar covalent or nonpolar covalent?

Calcium carbonate (CaCO3) is essentially an ionic compound with divalent calcium and carbonate ions. But the carbonate anion is a polyatomic species. The carbon atom is bonded to the three oxygen atoms by covalent bonds, two single carbon-oxygen bonds and a carbon dioxide double bond.

Covalent solid: also called a network solid where atoms are bonded by covalent bonds in a single continuous network. CaCO3: This compound is composed of Ca (a metal) and CO32- (a polyatomic ion) and dissociates into Ca2+(cation) and F–(anion). All Si atoms are connected to 4 oxygen atoms. This is a covalent solid.
