Melting point of Radon is -71 °C and its the boiling point is -61,8 °C. Atomic Number – Protons, Electrons and Neutrons in Radon. Radon is a chemical element with atomic number 86 which means there are 86 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. Radon är ett grundämne, en radioaktiv ädelgas, med beteckning Rn och atomnummer 86. Den vanligast förekommande isotopen är radon-222, som bildas vid sönderfall av radium-226 och ingår i den sönderfallskedja som börjar med uran-238 och slutar med bly-206.Radon-222, som har en halveringstid på 3,8 dagar, är en gas som sprids lätt från till exempel uran- och radiumhaltig berggrund in In the example, Rn is the atomic symbol for the element Radon.

Melting point of Radon is -71 °C and its the boiling point is -61,8 °C. » Boiling Point » Melting Point » Abundant » State at STP » Discovery Year. For stable elements, there is usually a variety of stable isotopes. Isotopes are nuclides that have the same atomic number and are therefore the same element, but differ in the number of neutrons.
