Differences Between Ionic and Covalent Compounds A compound is defined as the chemical combination of two or more elements. A chemical bond is the "glue" that holds atoms of different elements together. Bonds can be classified into two general types: ionic and covalent. Ionic bonds generally occur between a metallic atom and a nonmetallic atom.
