Which noble gas is not found in the atmosphere? (A) Argon (B) Krypton (C) Xenon (D) Radon

Nobel Gases in Atmosphere

Radon gas is the only noble gas that is not available in the Atmosphere. Apart from this, Helium, Neon, Argon, and other noble gases are present in the earth's atmosphere. the table below will explain the presence of all Noble Gases in the atmosphere.

• They are regarded as the most stable elements in the periodic table because their outer shell of valence electrons is thought to be "full," giving them minimal tendency to engage in chemical processes.
• Inert and rare gasses are other names for noble gasses.
• In an air separation unit, fractional distillation and gas liquefaction are used to separate out neon, argon, krypton, and xenon from air.
• Using cryogenic gas separation processes, helium is obtained from natural gas reserves where helium concentrations are high.

Summary:

Which Noble Gas is Not Found in the Atmosphere? (A) Argon (B) Krypton (C) Xenon (D) Radon

The noble gas radon is not present in the atmosphere. The radioactive decay of dissolved radium, thorium, or uranium compounds typically results in the isolation of radon. Radon gas is present in the modern periodic table.
