Yeah you pretty much place double bonds when you have more electrons on the Lewis structure than you actually need. Like if you need to have 10 Electrons but you have 12 on the structure, then you should replace a single bond with a double bond somewhere and remove one of the lone pair of electrons ...

Oxygen and Nitrogen are diatomic molecules. Therefore, by nature they appear as N2 and O2.

Photons can however, with enough energy, eject electrons. These electrons have mass and velocity and therefore, have momentum. So even though photons themselves don't have any momentum, their energy can create momentum on electrons.
