Let’s start off with the key definition for bases..

-          A base is a species that is proton acceptor (basically the opposite of an acid)

-          They produce a pH of greater than 7 in solution with water.. they’re BASIC

Common bases include metal oxides and metal hydroxides;

(you should learn these off by heart if you don’t know any already)

Metal oxides; MgO (magnesium oxide), CuO (copper oxide)

Metal hydroxides; NaOH (sodium hydroxide), Mg(OH2) (magnesium hydroxide)

And… AMMONIA (NH3)!! YOUR FAVOURITE.. RIGHT? Yeah mine too.. -_-
