Quick Answer: An ionic bond is formed when electrons are?

For example, the metal calcium (Ca) and the nonmetal chlorine (Cl) form the ionic compound calcium chloride (CaCl 2). In this compound, there are two negative chloride ions for each positive calcium ion. Are ionic bonds between two nonmetals? Ionic bonds form when a nonmetal and a metal exchange electrons, while covalent bonds form when

Properties of ionic, covalent, and metallic compounds

Ionic compounds tend to be crystalline structures with high melting points that are water soluble. Covalent bonds are highly stable bonds with low melting points. Many covalent compounds are flexible or gaseous and are not water soluble. Metallic compounds contain freely floating electrons which allow them to conduct electricity and heat well.
