What is noble gases?
The noble gases make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six naturally occurring noble gases are helium, neon, argon, krypton, xenon, and the radioactive radon.
What are the characteristics of noble gases?
The physical properties of noble gases are as follows; they are colorless, odorless, tasteless, and non-flammable under standard conditions. Noble gases have very low melting and boiling points. They are non-reactive in their natural state and commonly known as inert gases. The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.
