Explanation

The low chemical reactivity of noble gases can be attributed to their high ionization energies. Noble gases have a complete valence shell, making it difficult for them to gain or lose electrons and thus react with other elements.

Explanation

Argon makes up about 0.93% of the Earth's atmosphere, which is approximately 1%. This percentage makes argon the third most abundant gas in the atmosphere, after nitrogen and oxygen.

Explanation

Fluorine (F) forms a chemical compound with xenon (Xe) to form xenon hexafluoride ( ext{XeF}_{6}). This is one of the few examples where a noble gas forms a compound with another element.

Explanation

The last member of the inert gas elements, also known as noble gases, is Radon (Rn). It is the heaviest and the last naturally occurring noble gas in Group 18 of the periodic table.

Which of following is inert gas

Explanation

Argon is an inert gas. Inert gases, also known as noble gases, are found in Group 18 of the periodic table and include Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). Argon is commonly used in various applications due to its inert properties.

Which inert gas show abnormal behavior on liquefaction

You've reached today's free limit of 20 questions. Log in to keep practising for free.
Explanation

Helium (He) exhibits abnormal behavior on liquefaction. Unlike other inert gases, helium remains in a liquid state even at extremely low temperatures close to absolute zero. This is due to its very low boiling point and the weak interatomic forces present in helium atoms. Helium does not solidify under standard pressure and requires extremely high pressures to become a solid.
