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.

∙ 11y agoNoble gases have completely filled valence orbitals and are stable. Halogens have 7 valence electrons. They need one more to attain noble gas configuration and are hence reactive.

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 halogens are more reactive than noble gases?
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.
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 are the alkali metals and the halogens among the reactive elements an the periodic table?
alkali metals have one valence electron and halogens have 7. since elements always want to have a full outer shell, these two types of elements react easily with each other to form a full outer shell of 8 electrons.
Is mercury more reactive than zinc?
Zinc is more reactive than mercury.
Are halogens more reactive than actinides?
No actinides are more reactive

How do halogens differ from noble gases?
halogens are much more reactive
Is potassium more reactive than iodine?
No it is not for astatine is the weakest of halogens and can be displaced by other lighter halogens into salts.
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.
Why inter halogens are more reactive then halogens?
If they are more reactive, I would speculate it is due to their differences in electronegativities. The greater the difference, the more stable the compound. Electronegativities decrease as you go from F to I. For example, ClF3 reacts more violently than F2, yet IF7 is chemically inert. http://en.wikipedia.org/wiki/Interhalogen
Which is more reactive lithium in group 1 or neon in group 18?
neon is a noble gas that will not react with anything -- any other element except helium is more reactive than neon! With lithium, quite a reactive metal, it is certainly more reactive than neon.
How do the physical and chemical properties of the halogens comparew with those of the inert gases?
Halogens are very reactive both physically & chemically than that of inert gases ,as halogens have valency 1.
Is sulphur more reactive than phosphorus?
Sulfur is a fairly reactive non metal. It burns in air to form sulfur dioxide, it reacts with most metals to make ionic sulfides, and with halogens to make covalent compounds. It does not react with water or acids, but does react with hot alkalis.
What elements bond with iodine?
it bonds with many elements but it is less reactive than the rest of the halogens
