Oxygen has an electron configuration of 1s22s22p4.

Normally we do not use noble gas configuration for the first 18 elements. But, in the case of oxygen the noble gas would be Helium, one row up and over to the noble gas column.

Helium is represented by the 1s2 portion of the electron configuration. Therefore, the 1s2 can be replaced by the noble gas [He]. This makes the noble gas configuration for oxygen
[He] 2s^2 2p^4#.

I hope this was helpful.
