Yes. they do
Noble gases are nonmetals. They are colorless, odorless gases that are known for their low reactivity and full outer electron shells.
Noble gases are elements noted for extremely low electronegativity because of an outer valence that is complete. Therefore a false statement about Noble Gases would be that "Noble Gases have high electronegativity" or "Noble Gases are notorious for being extremely reactive elements."
The number of compounds of noble gases is very low; salts derived from xenon are known.
Noble gases have completely filled valence orbitals and are hence stable or chemically inert.
Very low activity.

Noble gases have completely filled valence orbitals and are hence stable or chemically inert.
The boiling points of noble gases are very low, ranging from -246.1C for helium to -268.9C for radon.
In strict logical inference, nothing, because there could be very dense nonmetals to compensate for the gases. However, in fact the densities of nonmetals on average are less than the densities of metals.
Very low activity.
Yes. They are also referred to as the inert gases.
Helium is a noble gas. It is part of the group of gases known as noble gases which have low reactivity due to their full outer electron shells.
Noble gases are known for their low reactivity because they have a full valence shell of electrons, making them stable and less likely to form compounds with other elements.
"Noble" gases have the outer electron shell full, with 8 electrons; this structure lead to a very low chemical reactivity but now they are not considered as inert elements.
Noble gsase are liquefied at very low temperatures, with many difficulties and expenses.
