Ionic bonds are chemical bonds that result from the electrical attraction between cations and anions. In ionic bonds, atoms give up electrons to other atoms.  Atoms in ionic materials have a strong attraction to other ions. Ionic solids tend to have the following characteristics:

• Crystal-like in structure

• They conduct electricity when dissolved in water or as a liquid

• They have high a high melting point

• They're soluble

•  They don't conduct electricity as a solid

Covalent bonds are bonds that result from the sharing of electron pairs between two atoms. In covalent bonds, the shared electron pair is owned equally by the two atoms.  Atoms in covalent materials are bound closely together in but aren't strongly attracted to each other. Covalent bonds have the following characteristics:

• They can be gases, liquids or solids

• They have low melting and points

• They conduct electricity poorly, no matter what form they're in

• They are somewhat soluble in non-polar liquids but not in water.

Metallic bonds are the result of attraction between positively charges atomic nuclei of metal atoms and relocalized electrons in the metal. There are strong bonds between the atoms, which is why they have high melting points. Metallic bonds have the following characteristics:

• They're usually shiny

•  They're not soluble

• They have high melting points

• They're conductive as either solids or liquids
