Radon is a naturally occurring radioactive element symbolized by Rn and atomic no. 86 in the periodic table. It is the heaviest known noble gas in the periodic Isotope: chemical element with the same atomic number and position in the chemical behaviour but with different atomic masses and physical properties.

Roentgenium was in fact discovered 10 years earlier on December 8, 1994, by a team of 13 nuclear physicists working at the Gesellschaft für Schwerionenforschung at Darmstadt in Germany carried out an experiment, bombarding a target of 209Bi with 64Ni ions. Properties of atomic nuclei (atomic mass, nuclear cross-sections) are determined by the number of protons and number of neutrons (neutron number). It must be noted, especially nuclear cross-sections may vary by many orders from nuclide with the neutron number N to nuclide with the neutron number N+1. Roentgenium is a synthetic radioactive metal, created via nuclear bombardment, and has only been produced in minute amounts.

Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.

Additional recommended knowledge. Roentgenium: isolation. Isolation: only a few atoms of element 111, roentgenium, have ever been made through a nuclear reaction involving fusion of an isotope of bismuth, 209 Bi, with one of nickel, 64 Ni. 209 Bi + 64 Ni → 272 Rg + 1 n. Isolation of an observable quantity has … Die chemiese element röntgenium (Rg), met ’n atoommassa van ongeveer 280 u, het geen stabiele isotope nie en word dus as ’n radioaktiewe element geklassifiseer. Die sewe isotope is onstabiel en het ’n relatief kort halfleeftyd (die meeste minder as ’n sekonde).. In die natuur kom geen röntgenium voor nie; alle isotope is sinteties in ’n laboratorium berei. Technetium-99 has also been proposed for use in optolectric nuclear batteries.
