Calcium carbonate is another example of a compound with both ionic and covalent bonds. ... These species share an ionic bond, while the carbon and oxygen atoms in carbonate are covalently bonded.

Can a bond have both covalent and ionic character?

The bond formed between any two atoms is not a purely ionic bond. All bonding interactions have some covalent character because the electron density remains shared between the atoms. ... Bonds that fall in between the two extremes, having both ionic and covalent character, are classified as polar covalent bonds.

Which among the following contains both ionic and covalent bond?

Only ionic compounds consisting of polyatomic ions contain ionic as well as covalent bonds. KCN consists of K+ and [:C≡N:]- ions. The bond between K+ and CN- is ionic while the bonds between C and N in cyanide ion are covalent.
