Covalent bonds are where eletrons are shared between the atoms. Each covalent bond prvides an extra shared electrons so that the atoms have a full outer shell. When atoms make covalent bnds with one or more other atoms; they form a molecule. A molecule is two or more atoms held together by covalent bonds; it occurs between two non metals.

Example of covalen bonds: Hydrogen, hydrogen and chloride, methane and oxygenn.

Iodine molecules are covalent bonds and are very strong. However their is a weak intermolecular force between the other covalent bonds in the element which means that they are usually found in a gas state…
