Answer:
A cation is a positively charged ion. Thus it has fewer electrons than protons. It 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.
Tip: A good way to remember this is, A Cation has a t in it, like a +; keep that in mind if you have trouble remembering which is a cation or a anion
