Bonds of Chemistry

Ionic Bond

Ionic bonds form from electrical attraction between cations and anions.

Atoms of ionic bonds give up electrons to other atoms of the same bond.

This bond is soluble, has a high melting point, is conductive as a liquid and when dissolved in water, and has a granular or powdery appearance. It is not conductive in its solid state.

Covalent Bond

There are two types of covalent bonds: Nonpolar Covalent and Polar Covalent. These bonds form from the sharing of electron pairs between two atoms.

Covalent bonds are soluble, have a low melting point, and appear granular or powdery. They are not conductive in any state.

Nonpolar Covalent bonds are where the electrons are shared equally between the atoms. These have a balanced distribution of electrical charge.

Polar Covalent bonds have an unequal attraction for the shared electrons. These have and uneven distribution of electrical charge.

The above scale can be used to help identify the identity of a bond.


Metallic bonds form from the attraction between metal atoms. The electrons of this bond are "delocalized" meaning they dont have a specific location.

This bond is conductive in every state that is applicable to the compound, has a high melting point, is malleable and ductile, and appears to be shiny. It is not soluble.
