Most gaseous elements are found on the right side and upper-right corner of the periodic table, plus hydrogen on the far left in period 1.

Quick Scoop

  • The naturally gaseous elements at room temperature are: H, He, N, O, F, Ne, Cl, Ar, Kr, Xe, Rn.
  • Except for hydrogen, they cluster in the upper-right portion of the table, where the nonmetals and noble gases are.
  • All noble gases (group 18, far right column) are gases, and several nonmetal elements just to the left of them (like N, O, F, Cl) are also gases.

So if you’re scanning a periodic table and wondering “where do the gaseous elements tend to be located?”, look mostly at the top right (nonmetals and noble gases) and don’t forget lone hydrogen on the top left.
