Difference Between Anions and Cations

Ions which are a part of the science subject Chemistry forms from atoms and electrons that have either gained or lost their weight by the removal or adding of one or more valence electrons which would create either positive or a negative charge. The ions with a negative charge are called anions and the ones with a positive charge are called cations. Since both of them have charges of opposing qualities, they get attracted to one another and thereby forming an ionic bond between them.

Difference Between Anions and Cations

When sodium a cation is depicted as NA+, the plus charge indicator shows that it has one electron less than the total number of protons. Thus sodium having an uneven distribution of electrons and protons enables it to have a  positive charge. Also the element chloride anion Cl- would denote that it has one less proton than the total number of electrons and giving it a minus charge. The difference between Anions and Cations are provided in the table listed below.

Difference Between Anions and Cations

          Basis             Anions       Cations
Definition An anion may be defined as an atom or molecule that is negatively charged. A cation may be defined as an atom or molecule that is positively charged.
Charge Type Negative Positive
Type of Element Non-Metal Metal
Type of Electrode used Anode Cathode
Examples Sulfide, Oxide, Fluoride, Chloride Iron, Lead, Sodium

The above differences would have given a clear picture of how these two ions that sound alike differ in nature during a chemical reaction in particular. For learning more interesting topics like this visit byjus.com
