Question

What is a “noble gas”

Answer 1

A noble gas refers to any of the elements in group 18 of the periodic table, also known as the "noble gases." These gases include helium, neon, argon, krypton, xenon, and radon. Noble gases are characterized by their extremely low reactivity due to their filled electron shells, making them stable and rarely forming chemical compounds with other elements. They are colorless, odorless, and tasteless at standard conditions and are commonly used in various applications such as lighting, lasers, cryogenics, and as inert atmospheres.
