Ionic  Bonds

Ionic bonding occurs when two atoms transfer valance electrons.  The metal atom loses an electron and becomes a positive cation, while the non-metal atom gains the electron and becomes a negative anion.

Characteristics of Ionic Bonds

Are soluble

High melting point

Liquid form is conductive

Covalent Bonds

Covalent bonding occurs when two atoms of the same element or which are near each other on the periodic table share electrons.

Characteristics of Covalent Bonds

Are soluble

Low melting point

Not conductive

Metallic Bonds

Metallic bonding is the sharing of free electrons among positively charged atoms.

Characteristics of Metallic Bonds

Not soluble

High melting point

Conductive in solid state
