What are the chem. formulas for elemental liquids and gasses at room temperature and pressure?

I guess you are asking elemental liquids and gasses like hydrogen, chlorine.. the chemical formula is determined by the postion in periodic table . Let say halogen, which is group 17, will exist as diatom, that is X2. Noble gas, group 18 will stay as monoatom because they have stable electron configuration.

Then we have others like P4, S8... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
