What does noble gas refer to?
: any of a group of rare gases that include helium, neon, argon, krypton, xenon, and usually radon and that exhibit great stability and extremely low reaction rates. — called also inert gas.
Which noble gas is the rarest?
xenon
The extremely rare noble gas xenon (Xe) only accounts for 0.000009% of air. It is only used where lighter noble gases are not effective.
What is a male noble gas?
The noble gases are: Helium (He) Neon (Ne) Argon (Ar) Krypton (Kr)
Can a noble gas freeze?
It has no melting point because it cannot be frozen at any temperature. The most important chemical property of the noble gases is their lack of reactivity. Helium, neon, and argon do not combine with any other elements to form compounds.

Are there any noble gases that have no color?
Noble gases. What are they? Well, noble gases are a group of non-reactive elements, which are odorless and have no color, under specific conditions. [1] Helium, neon, argon, krypton, xenon, and radon are all noble gases.
What are the physical properties of noble gases?
What are Noble Gases? 1 Properties of Helium (He) Helium is a chemical element which is denoted by the symbol He. The atomic number of helium is 2. Under standard conditions 2 Properties of Neon (Ne) 3 Properties of Argon (Ar) 4 Properties of Krypton (Kr) 5 Properties of Xenon (Xe)
Why are noble gases used in refrigerants?
Noble gases have very low boiling and melting points, which would make them very useful in refrigerants. They are also commonly used in lighting. That is because of their ability to not react to most chemicals. That makes noble gases perfect in lighting. [1] Helium is one of the noble gases.
