Water can be used as the best example.  It has two Hydrogen atoms and only one oxygen atom.  Hydrogen contains only one electron in its outer shell.  Oxygen contains eight electrons, two in the inner shell and six in the outer shell.  Eight electrons are needed to maintain atom stability in oxygen, whereas Hydrogen only needs one more electron.  Oxygen has six and still needs two more electrons to stabilize.  Hydrogen has one and needs only one more electron to stabilize.  Each Hydrogen shares one pair of electrons giving a Hydrogen atom a capacity of just one.  Oxygen shares two pairs of electrons giving Oxygen the capacity of two.
