What else can I help you with?
What is another name for the noble gases?
pure or inert gasses
Which element exisit in its pure form?
most noble gases exist in their pure form because they are so unreactive
Is neon being used as a compound or pure element?
Neon is an element . . . one of the noble gases.
Why are noble gases found in their pure uncombined form in nature?
Noble gases are found in their pure uncombined form in nature because they have a full outer electron shell, making them stable and chemically unreactive. This stability prevents them from forming compounds with other elements, allowing them to exist in their elemental form.
Is air a pure elemental substance?
No. Air is a mixture of gases, predominantly nitrogen and oxygen but also including carbon dioxide, water vapor, and noble gases.
What is the importance of fractional distillation to separate components of air?
Cryogenic distillation of air is a method to obtain pure noble gases.
Is helium a mixture or a pure substance?
Yes, it is a pure substance but can be mixed with other gases.
What noble gases is red?
Neon glows reddish-orange in a vacuum discharge tube
Does xenon have an odor?
No. Xenon is an odorless gas, as are all noble gases.
Is radon found in pure state or mostly in compounds?
The element, Radon is one of the Noble Gases like Helium and Neon that do not form compounds. Thus Radon is always found in the Pure State.
What are the only elements that are distinct in nature as uncombined atoms?
The noble gases generally exist in nature in monoatomic form. Some metals are unreactive enough to exist in nature as pure "nuggets" of metal; gold is probably the most notable, but there are places where one can find nuggets of (nearly) pure copper as well.
What elements are inert gas often made of?
Inert gases contain elements that aren't likely to chemically react. Noble gases are the best candidates, since their valence electron shell is completed and thus are really unlikely to react with another atom, but nitrogen (which isn't a noble gas) also is a good inert gas.
