No. Ionic bonds form when atoms with opposite charges bond with one another. Atoms develop charges by gaining or losing electrons. For a given element, the atoms will (usually) have a tendency to gain OR lose a particular number of electrons, so they can only form ions of a particular charge that is either positive or negative.
Both of them have a shell with a living organisms with the valves and they both are form somewhere different
