What are 4 physical properties of noble gases?
Noble gases, which include helium, neon, argon, krypton, xenon, and radon, are colorless, odorless, and tasteless gases under standard conditions. They have low boiling and melting points compared to other elements, and they possess very low chemical reactivity due to their complete valence electron shells. Additionally, noble gases have low densities and are excellent insulators of electricity.
Are noble gases metals or nonmetals?
Noble gases are nonmetals. They are colorless, odorless gases that are known for their low reactivity and full outer electron shells.
What is a false statement about noble gases?
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."
Are noble gases known for forming salts?
The number of compounds of noble gases is very low; salts derived from xenon are known.
Does noble gases react high or low?
Noble gases have completely filled valence orbitals and are hence stable or chemically inert.

Does noble gases react high or low?
Noble gases have completely filled valence orbitals and are hence stable or chemically inert.
What are the boiling points of noble gases?
The boiling points of noble gases are very low, ranging from -246.1C for helium to -268.9C for radon.
Given that a large number of non-metalsare gases what does it tell you about the densities of non-metals in general?
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.
What are noble gases relative activity?
Very low activity.
Are the noble gases very stable and have low reactivity?
Yes. They are also referred to as the inert gases.
Is helium a noble gas or a chemical?
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.
Are noble gases high or low reactivity?
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.
Why are the noble gases noble?
"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.
