Why are the halogens so reactive and noble gases not reactive?

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.

Is the group halogens in a periodic table reactive?
Very much so. The only group that isn't reactive is the Noble gases, however even some noble gases will react under the right conditions.
How many electrons are present in the valence level for all noble gases except helium?
There are eight in all noble gases (except helium) because that forms a "full level" so that they are noble gases and not reactive.
Why are noble gases almost non-reactive?
Noble gases have completely filled orbitals / electron energy shells. They are stable and chemically inert (non-reactive). So generally they will not accept / gain / share electrons and they do not form compounds.
Are helium and krypton similar or different in reactivities?
Pretty similar. They are both are noble gases, so they are both very non-reactive. Noble gases rarely form compounds.
How do electron configurations of noble gases give them high unreactivity?
Noble gases have completely filled orbitals, are stable and chemically inert (non-reactive). So generally they will not form compounds.

How do halogens differ from noble gases?
halogens are much more reactive
Why noble gases are highly reactive?
Noble gases are not reactive. They are inert. That's why they are called noble gases. Just as the human nobility does not lower itself to associate with the lower classes, so do noble gases not combine with lesser elements. They remain aloof.
How are halogens and noble gasea differ?
One is chemically reactive(Halogens) and one is very hard to react with other elements, natural or man-made(Noble Gases). Such as Hydrogen used to be used as the gas to keep blimps floating, and it was found to be too dangerous, so it was changed to Helium(Noble Gas). Hope I was able to help!
Why is a noble gas inert?
Noble gases have a stable electron configuration. So they are less reactive.
How many electrons are present in the valence level for all noble gases except helium?
There are eight in all noble gases (except helium) because that forms a "full level" so that they are noble gases and not reactive.
Why are noble gasses are so unreactive?
Noble gases have completely filled outer electronic configuration. Hence they are non-reactive.
Why are noble gases almost non-reactive?
Noble gases have completely filled orbitals / electron energy shells. They are stable and chemically inert (non-reactive). So generally they will not accept / gain / share electrons and they do not form compounds.

What family contains elements that will not form compounds metalloids halogens noble gases strong metals?
Remember a family is also a group, so 3A - 7A.
The most charateristic property of the noble gases is?
Noble gases have completely filled orbitals. They are stable and chemically inert (non-reactive). So generally they will not accept / gain / share electrons and they do not form compounds.
