Noble gases have completely filled orbitals and hence are generally chemically inert. Halogens are highly reactive as they need one more electron to complete octet.
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).
They are completely different Noble gases are colorless, monoatomic gases; the halogens are diatomic, colored and there form at room temperature is F, gas, Cl, gas, Br, liquid I, solid. Nobel gases are chemically unreactive, helium and neon have no known compounds, a few very reactive compounds are known for the rest. The halogens are all reactive, fluoringe is the most reactive. One or more of the halogens will form compounds with all of the other elements apart from the noble gases. (apart from He and Ne)
Halogens are extremely reactive, noble gases are very unreactive. All noble gases are gases; only F and Cl are gases.
Halogens are reactive and they react with noble gases because they are not satisfied with the numbers of electrons they've got
Noble gases are chemically inert. They have completely filled orbitals, hence are generally non-reactive (or chemically inert).

halogens are much more reactive
halogens are reactive gases and noble gases are non reactive!=)

Noble gases are not reactiveHalogens are very reactive.
Noble gases are chemically inert. They have completely filled orbitals, hence are generally non-reactive (or chemically inert).
Because noble gases don't need to give or take any electrons - they have a perfect octet configuration. Where as halogens need to gain or lose electrons and will easily react to other halogens that need to lose or gain.
I think alkali is the most reactive one.
Noble gases have completely filled orbitals and are stable. Halogens have 7 valence electrons, they need one more to attain stability and are reactive.
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.
