The densities of the noble gases increase with increasing molecular mass. The increase in density is due to the increase in Atomic Mass. Helium is about one seventh the density of air and can be used in balloons and lighter-than-air craft. Xenon is about five times the density of air.

What is the trend in density as you go down the group of noble gases?
The densities of the noble gases increase with increasing molecular mass. The increase in density is due to the increase in atomic mass. Helium is about one seventh the density of air and can be used in balloons and lighter-than-air craft. Xenon is about five times the density of air.
Why are the noble gases not included in the trend in ionization energy?
Noble gases have completely filled orbitals are are stable. they do not donate electrons and hence are not included in ionization energy trend.
What happens when two noble gases are combined?
Noble gases do not react chemically with other noble gases.
What are the noble gases in Column 18 called?
inert gases / noble gases
What state are noble gases at room temperature?
Gases, hence noble "gases"

The elements that do not ordinarily form compounds are?
Noble gases do not normally form compounds.
What happens when two noble gases are combined?
Noble gases do not react chemically with other noble gases.
Which group of elements is very stable and nonreactive?
The class of noble gases (Helium, Neon etc. in group 18) There are two groups that come to mind when talking stability: the noble gases and the coinage metals. The noble gases (He, Ne, Ar, Kr, Xe, and Rn) are very chemically stable and do not readily form compounds. Note that although Radon is chemically stable, it's not stable from a nuclear standpoint and will decay (but it is not reactive in the chemical sense). The coinage metals (such as gold, silver, and copper) are very unreactive. Note that the further an element is from Au on the periodic table, the more reactive it is (obviously the Noble gases do not follow this trend).
What are the noble gases in Column 18 called?
inert gases / noble gases
What state are noble gases at room temperature?
Gases, hence noble "gases"
What is the heaviest elemet of the noble gases?
Down the group the density generally increases. Thus radon will be the heaviest element.
What are the elements in Group 17-18 called?
The Group 18 elements are called the noble gases or sometimes inert gases. Wikipedia has information on the noble gases, and a link is provided.
How are noble gases different than noble gases?
it's not
How active is noble gases?
Noble gases are chemically inert.
Who started the noble prize trend?
alfred noble
