Chemistry - Chemical Formulae - Formula for Covalent Bonds

Single Covalent Bonds

In covalent bonding, pairs of electrons are shared between the two non-metals.

A shared pair of electrons is called a single covalent bond, and each atom contributes one electron to the bond.

A single covalent bond is shown using a single line, for example H2 is written as H-H

Both the non-metals now have full outer shells of electrons. This arrangement of electrons will be the same as in the noble gases, and this is a very stable arrangement.

 

Multiple Covalent Bonds

Sometimes molecules share more than one pair of electrons in order to achieve full shells of electron.

If two pairs of electrons are shared then a double bond is formed, and if three pairs are shared then a triple bond is formed.
