Which group of the Periodic Table contains two elements that are gases at STP? Among the halogens, fluorine (F) and chlorine (Cl) are gases at STP. In the new, IUPAC approved system, the halogens are placed in group 17. In the two (ambiguous) older systeâ¦ms, their group might be labelled VIIB or VIIA. Making the world better, one answer at a time.
The elements that are gases at room temperature include hydrogen. They also include all the inert or noble gases, which are those elements in Group 18: helium, neon, argon, krâ¦ypton, xenon and radon. We also know that the halogens fluorine, chlorine and bromine are gases at room temperature (20Â°C). That leaves nitrogen and oxygen as the last of the elements that are gases at room temperature. All of these elements are nonmetals or halogens or inert gases. LAUGH OUT LOUD.
