Chromium Iii Sulfate Ionic Or Covalent

The compound chromium III sulfate is ionic in nature. This is because it consists of a metal cation, Cr3+, and a polyatomic anion, SO42-, held together by ionic bonds, which are electrostatic attractions between oppositely charged ions. The metal cation loses electrons to form a positively charged ion, while the non-metal polyatomic anion gains electrons to form a negatively charged ion. These opposite charges attract each other and result in the formation of an ionic compound.
