Making the world better, one answer at a time.
Elements of the periodic table that are gases are just called gases. There is a whole group of elements in the table that are gases, and they're the inert gases or noble gases â¦ . They comprise the elements of group 18 in the table.The inert gases are helium, neon, argon, krypton, xenon and radon.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.
