What are noble gases and how are they useful?
The group consists of 7 elements: helium, neon, argon, krypton, xenon, and radon. These elements are gases at ordinary room temperature and pressure. Noble gases are characterized by: The lack of reactivity makes these elements useful for many applications. They can be used to shield reactive chemicals from oxygen.
What are the noble gases in order?
Noble gas. This chemical series contains helium, neon, argon, krypton, xenon, and radon. The noble gases were previously referred to as inert gases, but this term is not strictly accurate because several of them do take part in chemical reactions.
Why don’t noble gases form many compounds?
With a great enough energy supply, the outer electrons of a noble gas can be ionized, and once the gas is ionized, it can accept electrons from other elements. Even under these conditions, noble gases do not form many compounds. Only a few hundred are known to exist. Examples include xenon hexafluoride (XeF 6) and argon fluorohydride (HArF).
