What type of bond is barium nitrate?

Answer 1

A chemical compound such as barium nitrate never "is" any type of chemical bond; instead, the compound "has" or "contains" pairs of atoms joined by such bonds. Barium nitrate happens to contain both of the most common types of bonds: Barium cations are bound ionically to polyatomic nitrate anions, and the nitrate anions are internally bonded by three covalent bonds between the sole nitrogen atom and each of the three oxygen atoms.
