Elements combine in three general ways. In<u> ionic</u> compounds, electrons are transferred from one element to the other, whereas in <u>covalent </u>compounds, electrons are shared between atoms. Third, in <u>metallic </u>bonding, electrons are shared between a large number of atoms in an electron sea.
Ionic compounds are compounds in which a free electron is transferred to another atom and a bond is formed. Ionic bonds occur in metal ions.
In liquid compounds, covalent bonds are formed. In covalent bonds, electrons are shared with each other,
The third type of bond is the metallic bond. In this type of bond, atoms are packed tightly and a free electron pool travels in between them.
