Hello Vashaanth,
I hope the picture above helps. As you see ozone is very unstable and constantly oscillating between the two structures shown above. A line at an O represents two dots (imagine they are linked to pairs).

The picture is from Wikipedia: https://de.wikipedia.org/wiki/Datei:Ozon_Mesomerie.svg and under CC-by-sa-License (i.e. you can use it for free).

If you have further questions do not hesitate to ask!

Kind regards, Okapi
