Why are the halogen family and noble gases alike and different?
Well the halogen family is very reactive and the noble gasses are not reactive at all.
What is the least reactive element?
The noble gases: Helium, neon, etc.
How do psychical and chemical properties of halogens compare with those of the inert gas?
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).
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 do the physical and chemical properties of the halogens compare with those of the noble glasses?
Halogens are extremely reactive, noble gases are very unreactive. All noble gases are gases; only F and Cl are gases.
Why are the halogen family and noble gases alike and different?
Well the halogen family is very reactive and the noble gasses are not reactive at all.
What elements are considered not very reactive?
Noble Gases
Why are noble gases very reactive?
Nobel gases are very unreactive.
Why are noble gasses called inert gasses?
With very few exceptions (you can make argon fluorides, but you have to work at it), the noble gases are nonreactive--they won't form compounds.
How reactive is it xenon?
It is a noble gas and so very unreactive.
What is the least reactive element?
The noble gases: Helium, neon, etc.
How do physical and chemical properties of the halogens compare with those of the noble gases?
Noble gases are not reactiveHalogens are very reactive.
How many compounds are there for krytpon?
Only one compound has been formed with krypton. Krypton is very nonreactive becuase it is a noble gas. Like all noble gasses, its valence electron shell is filled.It can react with flourine because flourine has the highest electronegativity of any element, making it highly reactive.

Is oxygen more reactive then the noble gases?
Yes. The noble gasses are very stable because they have 8 valance electrons. They rarely react. However, oxygen only has 6 valance electrons, so it wants two more. It will most likely react with a group II metal to gain the 2 electrons.
What element is more reactive Be or Ar?
Berylium is a alkaline earth metal and is fairly reactive. Argon is a noble gas that is very unreactive. Therefore Be is more reactive
