Question

name rare gas - Helium or Neon

Answer 1

Neon (Ne), Krypton (Kr) and Xenon (Xe) are termed as rare gases as they are present in air in very low concentrations. Neon, Krypton and Xenon remain in the air because they do not combine with other materials to form solid or liquid compounds. All of these gases are monatomic. They are also called inert gases or noble gases.
