Halogens have 7 valence electrons and nobel gases have 8.
Each atom wants 8 or none electrons according to the octet rule.
Therefore, nobel gases are relatively unreactive b/c they already have 8
Halogens only need 1 more valence electron, making them very reactive.

Which are more chemically reactive halogens or noble gases?
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.
What do halogens and noble gases have very different chemical properties?
Noble gases have completely filled orbitals and are stable. Halogens have 7 valence electrons, they need one more to attain stability and are reactive.
How do the properties of the halogens and noble gases compare?
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)
Why are noble gases less reactive than halogens?
Noble gases all have 8 electrons in their outter most energy level. when an atom has 8 electrons in it's outtermost layer, then its more stable
Why is halogens more reactive than noble gas?
Halogens are reactive because they don't have a full octet. Noble gases are inert because they have a full octet. In order for a halogen to fulfill it's octet it must gain an electron. The electron usually comes from another atom such as sodium or another alkali metal but the electron can come from another source.

How do halogens differ from noble gases?
halogens are much more reactive

Is the carbon family or the noble gases more reactive?
the carbon family. the noble gases never react
How is the halogen family and the noble gas family different?
The noble gases have completely filled orbitals and are hence generally stable and chemically inert. The halogens need one more electron to complete octet and are generally highly reactive.
Is chlorine more reactive with oxygen than argon?
Yes. Argon is one of the noble gases with a valence configuration of 8 electrons. All of the noble gases are the least reactive elements.
What is the reactivity for nonmetals?
Fluorine Chlorine Iodine Bromine Astatine
Is noble gases metals that are more reactive than the transition elements but less reactive than the alkali metals?
No, the noble gasses are nonmetals that are less reactive than all other elements.
Why noble gases react with fluorine as you know noble gases are more stable?
Because fluorine is having the most electronegativity and is the most reactive non metal.
