Which noble gas is the heaviest based on the standard group of noble gases?

• A. Helium
• B. Xenon
• C. Radon
• D. Argon

Answer: (C)

Radon is the heaviest noble gas in the standard group of noble gases. The noble gases, which include helium, neon, argon, krypton, xenon, and radon, are known for their low reactivity and unique properties. In terms of atomic mass, radon has a higher atomic weight compared to the other noble gases, making it the heaviest among them. Helium, being the lightest noble gas, has a very low atomic mass. Argon and krypton also have atomic masses that are significantly lower than radon. While xenon is heavier than both argon and krypton, it still does not surpass radon's atomic weight. This relationship among the noble gases is an essential aspect of understanding their properties, behavior, and applications in various fields, including chemistry and physics.
