Cation vs. Anion — What's the Difference?

An ion or group of ions having a positive charge and characteristically moving toward the negative electrode in electrolysis.

A negatively charged ion, especially the ion that migrates to an anode in electrolysis.

(physical chemistry) a positively charged ion, i.e. one that would be attracted to the cathode in electrolysis

A negatively charged ion.

A positively charged atom, radical, or molecule, which in electrolysis migrates to the cathode; a positive ion; - opposed to anion.

An electro-negative atom or group of atoms, or the element which, in electro-chemical decompositions, is evolved at the anode; - opposed to cation.
