Dear student 
Here are several examples of anions:
Bromide - Br -
Chloride - Cl -
Fluoride - F -
Iodide - I -
Nitride - N 3-
Oxide - O 2-
Sulfide - S 2-
An example of a cation would be the sodium cation when it dissociates from chlorine anion. The sodium has its electron taken from it by chlorine, becoming positive. An easy way to remember that cations are the ions with a positive charge is to remember the phrase "cats are positive
