I want to know if there's any substance that is liquid at room temperature and atmospheric pressure that doesn't contain HYDROGEN atom(s) in its make up. Any substance dissolved in water or any substance that contains HYDROGEN is not required 




You are not going to get a list of compounds which fit your description. It's a very general question. However, many compounds of the form $\ce{C\_nX\_{2n+2}}$, where X is a halogen for example, are liquids at room tempterature, and contain no hydrogens. 


Examples: 


[Perfluorooctane:](https://en.wikipedia.org/wiki/Perfluorooctane)

Melting point: $-25^o C$, Boiling point $103^oC$

Melting point: $-37^o C$, Boiling point $76^oC$

Melting point: depends on the isomer, Boiling point $142^oC$


You can read about [fluorocarbons](https://en.wikipedia.org/wiki/Fluorocarbon). Many of these are liquids.

Yes. Bromine. Melting point: - 7.2 degree Celsius, boiling point: + 58.8 degree Celsius

Carbon disulphide and bromine are both liquids at room temperature and atmospheric pressure. They do not contain hydrogen atoms. Some elements become liquids at or near room temperature they include gallium, caesium and francium .I'm sure they're still other substances that are liquids at room temperature and atmospheric pressure.

One could make the argument that gallium is a liquid at room temperature, if you're willing to fudge a few degrees and go up to 30 C. Say "room temperature on an unseasonably warm day".
