The scale you seek is Mohs' scale and applies only to solids. Mohs devised this scale about 1812 where talc is 1, gypsum is 2 up to diamond 10. Neon gas would not come under this scale.

It is about 2.5 in the Mohs Hardness Scale.
where is rock salt on the moths hardness scale
The Mohs Scale of Hardness determines the hardness of minerals by scratching them with commonly found objects. The minerals are assigned a number which corresponds to their hardness; higher numbers indicate higher hardness.
The element neon has no hardness on either moh's hardness scale or rockwell scale unless it is frozen. These scales measure only solids.
The hardness of Limonite is 4 t0 5.5 on the mohs hardness scale.
