What Is The Rarest Gas On Earth?

Among all the many elements there are six elements that are gases and that are grouped together by scientists. These are the noble gases. The noble gases are a unique grouping of elements found naturally on Earth. 

These elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). 

Helium – Helium (He), chemical element, Group 18 inert gas (noble gasses) of the periodic table and the second lightest element.

Neon – Neon is a chemical element with the atomic number 10 and the symbol Ne. It’s a fuel that is precious.

Argon – Argon is a chemical element with Ar and atomic number 18 symbols. It is a noble gas, in group 18 of the periodic table.

Krypton – The krypton chemical element is classified as a noble gas and an atomic number 36 non-metal.

Xenon – Xenon (Xe) is a colorless, odorless gas that belongs to the noble family of elements,

Radon – Radon is a toxic gas which spontaneously breaks down into rocks, soil and groundwater as plutonium, thorium, and radium, which are radioactive metals.
