Which element is a noble gas that is unreactive?
Helium, Neon, Xenon, Krypton, Radon, and Argon.
What are the gasses in the periodic table that are unreactive?
The noble gases are extremely stable and have an octet (eight electrons in their outer shell with the exception of helium that has two). The far right group on the periodic table contains the noble gases such as helium, neon, argon, krypton, etc.
What is helium's reactivity ability?
Helium is totally unreactive.
Does helium change into a different substance?
Helium is unreactive.
The noble gases include helium neon argon krypton xenon and radon. What property do these elements share?
They readily form compounds with other elements.

What is the chemical property of the element krypton?
Krypton is an unreactive gas.
What is helium's reactivity ability?
Helium is totally unreactive.
Does helium change into a different substance?
Helium is unreactive.
What elements do no react with other elements?
Elements that are extremely unreactive include: Platinum (Pt), Gold (Au), Helium (He), Argon (Ar), Xenon (Xe), Krypton (Kr). These are unreactive because: Platinum and Gold are the bottom two elements in the metals Reactivity series. The rest are inert gases which are all unreactive.
What elements are almost completely unreactive with other elements?
The elements in group 8 - the noble gases (helium, neon, argon, krypton, xenon and radon) - are completely unreactive, as they have a complete outermost energy level ie. a perfect electron configuration.
Why doesn't krypton have an oxidation number?
Along with helium, argon neon radon and xenon, krypton is a "noble" gas that had a full outer electron shell, and does not react with other things.
What is the most unreactive gas?
Helium.
Is helium expolsive?
No, it is completely unreactive.
The noble gases include helium neon argon krypton xenon and radon. What property do these elements share?
They readily form compounds with other elements.
Why are there no compounds at all with helium in them?
Because helium is an unreactive chemical element.
