Types of Bonds
Ionic bonds are formed whenever a nonmetal element and a metal element share electrons. Ionic bonds are unique in that they dissolve in water, have high melting points, and do not conduct electricity as a solid.
Metallic bonds are formed when two metal elements come together and share and electrons. Metallic bonds are different from the others by having high melting points, having a shiny appearance almost all of the time, they don't dissolve in water, and they do conduct electricity as solids.
Covalent bonds are created when two nonmetal elements share electrons. Covalent bonds dissolve in water, and they do not. Induct electricity as a solid.
