What is a covalent compound?

A covalent compound is a compound  that is made up of two or more non-metallic elements that are joined together by covalent bonds. 

Many covalent compounds exist as individual units called molecules. eg. water

Covalent bonds

The non-metallic atoms within a molecule are joined together by covalent bonds.

Dash diagrams can be used to show the covalent bonds within a molecule.

Each dash is a covalent bond. Methane, CH4, has four covalent bonds.

A covalent bonds involves the sharing of two  electrons between atoms.

In methane, CH4 an atom of carbon shares its electrons with four atoms of hydrogen producing four covalent bonds.
