they have similar properties
Halogens are extremely reactive, noble gases are very unreactive. All noble gases are gases; only F and Cl are gases.
halogens and noble
Halogens
At room temperature the lighter halogens, F, Cl are diatomic gases, Br is a liquid, I is a solid. All of the halogens are colored and toxic. The noble gases are all colorless odorless non chemically toxic monoatomic gases. (Radon is radioactive).
atomic number fall into groups and periods....groups two of which are halogens and noble gases... means halogens and noble gases are related to each other by groups... hope i helped...

Halogens can be gaseous, liquid or solid; noble gases are only gases.Halogens are very chemical reactive elements; only some compounds of noble gases are known.

halogens are much more reactive
