Group 18 Elements (Noble Gases)

Noble Gases: The elements Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe) and Radon (Rn) constitute group 18 of the long form of the periodic table. Except for Rn, all other elements are present in the atmosphere in very small quantities, and hence, they are known as Rare gases of the atmosphere. Sometimes,

Inertness of Noble Gases

Inertness of Noble Gases: The combining capacity of atoms of elements to form molecules is known as valency. Different elements have different combining capacities. For instance, chlorine combines with one atom of hydrogen to form HCl; oxygen combines with two atoms of hydrogen to form H2O and nitrogen combines three atoms of hydrogen to form
