hydrogen, nitrogen, oxygen, fluorine, and chlorine are all 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 systems, their group might be labelled VIIB or VIIA.
All solids have a definite shape and volume.All elements are solid except for theNoble gases and hydrogen, nitrogen, oxygen, fluorine, and chlorine which are gases andthe liquids are usually Bromine and Mercury but Bromine would be a solid at STP.
The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
There is no method to designate such properties. Only symbols with atomic number are mentioned.
Xenon is a gas at STP. Gases are not malleable.
They are both elements, they are both gases at STP.

ITS A NON METALIt's a gas, one of the so called noble gases because of its reluctance to form compounds with other elements at STP. Other noble gases at STP include helium, argon, krypton, xenon and radon
The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
Fluorine and chlorine.
Noble gases have completely filled valence orbitals. Helium has 2 valence electrons, whereas other noble gases have 8. They are generally chemically inert at STP.
There is no method to designate such properties. Only symbols with atomic number are mentioned.
Elements of Group 18 may be called as;1-Noble gases 2-Rare gases 3- Inert gases
Another name for noble gases is inert gases.
