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
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.
