Are halogens inert gases?

No. halogens are not inert gases. Halogens are group 17 elements. Inert gases or noble gases are the group 18 elements Helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe) and radon (Rn) are the six inert gases.

What are the similarities of halogens and noble gases?

Halogens and noble gases are both elements found in group 18 of the periodic table. They are both inert gases with low reactivity. However, halogens are highly reactive nonmetals that readily form compounds, while noble gases are known for their stable and unreactive nature.


Which period contains the most elements that are all gases at STP?

The noble gases in Group 18 contain elements that are all gases at standard temperature and pressure (STP). Therefore, the period that contains the most elements that are all gases at STP is the third period.
