Cation Notes:
A positively charged ion is a cation. If kept in a electric field, these ions will be attracted to the negative charge and will move towards the negative pole of the electric charge. Cations with multiple charges may be given special names. For example, a cation with a +2 charge is a dication. One with a +3 charge is a trication. A zwitterion has both positive and negative charges at different regions of the molecule, yet an overall neutral charge. The symbol for a cation is the element symbol or molecular formula, followed by a superscript of the charge.
