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.
No, they are not. Fluorine, chlorine, and iodine are halogens, meaning they have 7 valence shell electrons. They are the second most nonreactive group of elements, besides the noble gases, which have 8 and do not react at all.
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.

halogens are much more reactive
Halogens are extremely reactive, noble gases are very unreactive. All noble gases are gases; only F and Cl are gases.
Noble gases are not reactiveHalogens are very reactive.
No, they are not. Fluorine, chlorine, and iodine are halogens, meaning they have 7 valence shell electrons. They are the second most nonreactive group of elements, besides the noble gases, which have 8 and do not react at all.

Halogens are highly reactive elements because they have seven valence electrons and are only one electron away from achieving a stable electron configuration like the noble gases. This electronic configuration makes halogens more likely to react with noble gases to gain that missing electron and achieve stability by forming compounds.
Noble gases are chemically inert, meaning they are generally non-reactive with other elements. This is due to their stable electron configuration, with a full outer shell of electrons. This makes noble gases very useful in applications where a non-reactive atmosphere is required.
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration. Hence they are chemically inert and generally donot form compounds under normal conditions.
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.
I think alkali is the most reactive one.
