They are found in group 18 â¦ on the periodic table (far right edge) of elements (He, Ne, Ar, Kr, Xe, and Rn).he only other elements that are gases at room temperature are hydrogen, oxygen, nitrogen, and then fluorine and chlorine. Those last two elements are part of group 17, which is the group known as halogens.   A link to the Wikipedia periodic table is posted.
