Atoms can also attain a stable electronic configuration through the sharing of electrons. This happens when non-metals react. This is because they both need to gain electrons. Both the nuclei of the atoms attract the electrons. This force is called the covalent bond. Once a covalent bond is formed, it is called a molecule.$^0$
Molecular compounds have a lower melting and boiling point. This is because the intermolecular forces(force between molecules) is weak. Thus it does not take much energy to break up the lattice and separate the molecules from each other.$^0$
Molecular compounds are also, generally, insoluble in water.$^0$
Molecular compounds do not conduct electricity as they are not composed of charged particles.$^0$
