what is a Cation
A cation is a postively-charged ion; cations are not normally found on the periodic table but the alkali metals and the alkaline earth metals typically become cations. In meta â¦ llic bonding, the delocalisation of the outer electrons means that metal cations are in a lattice of electrons.t is also attracted to the cathode in the process of electrolysis. A negatively charged ion, which has more electrons than protons, is called an anion.. An ion or group of ions having a positive charge and characteristically moving toward the negative electrode in electrolysis.
