There are two major resonance contributors for ozone (#O_3#)


A stable resonance structure is one where the greatest possible number of atoms obey the octet rule, with the least possible separation of charge.

You could draw these two
The two resonance structures of #O_3#

These are the two major resonance contributors (most stable).

Two minor structures can be drawn as well:
You can see that both have atoms that do not obey the octet rule and are therefore both minor contributors (and thus less stable)
