Red ball=Oxygen atomSprings=covalent bonds
The photograph above shows the oxygen molecule that contains two oxygen atom and two covalent bonds. The formula for oxygen molecule can be written as O2. Oxygen molecule is bonded in a linear structure where two atoms are at 180 degree from each other. Also, the photograph shows that the oxygen molecule followed the octet rule based on Lewis structure by forming double bonds between two oxygen atoms and making 2 lone pairs in each atom.
