Radon is described as what?

Radon is described as what?

• A. Chemically inert
• B. Non-radioactive
• C. Highly reactive
• D. Liquid at room temperature

Answer: (A)

Radon is chemically inert because it’s a noble gas with a full outer electron shell, which makes it very unlikely to form chemical bonds under normal conditions. This inertness is the property the statement highlights, capturing why radon doesn’t readily react with other substances. In reality, radon is radioactive, so the option describing it as non-radioactive is false. It isn’t highly reactive—noble gases like radon have minimal tendency to react, except in extreme circumstances. And at room temperature it exists as a gas, not a liquid (its boiling point is far below room temperature). So the description that best fits radon is its chemical inertness.
