Pure gas is not another name- inert gas is - although this is has been superseded by noble gas as chmical compounds have been discovered for the heavier noble gases since 1963.

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
Why are noble gases found in their pure uncombined form in nature?
The noble gases are always found pure because they already have their full set of valence electrons. They don't need to share or transfer any of their electrons with the other molecules.
Is neon being used as a compound or pure element?
Neon is an element . . . one of the noble gases.
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.
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 element is least likely to combine with another element for form a compound?
The elements in the family Group 0 - Inert Gases (exc. Radon) will not usually combine with other substances, as this group is highly unreactive. Inert Gases; Helium Neon Argon Krypton Xenon (Radon)
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.
Why were the noble gases the last elements to be discovered?
They do not exist in a stable natural state. They had to be made by man in the same way as many of the Actinides This is wrong. Unlike most actinides, they all exist as stable isotopes and some are reasonably common. The main reason is that they are very chemically similar to one another and thus are hard to isolate as pure elements. this is rite...
Where is the most reactive gas found?
Not counting the Noble Gases in the last group of the Periodic Table, the most active elements are located at the lower left and upper right. Assuming you are talking about pure, elemental gases, that would make Fluorine the most active gas.
