Their use has subsequently revolutionized medicine, found wide application in technology and heralded the age of modern physics, which is based on atomic and nuclear properties. In 1901, six years after their discovery, the benefit of X-rays to mankind was so evident that Roentgen was awarded the first Nobel Prize in Physics.

Technetium in the environment. Technetium is rarely encountered outside nuclear facilities ar research laboratories. World production of technetium runs to many tonnes because this element is extracted from spent nuclear … Roentgenium has 7 isotopes whose half-lives are known with mass numbers from 272 to 282. None of these isotopes are stable except for isotope is 281 Rg that is considered as the most stable isotope with a half-life of 23 seconds.

Roentgenium is calculated to have similar properties to its lighter homologues — copper, silver and gold — although it may show some differences as well. It is predicted to be a noble metal, and it is expected to be a solid under normal conditions and to crystallize in the body-centered cubic structure.

The number of electrons in each of Roentgenium's shells is 2, 8, 18, 32, 32, 18, 2 and its … 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. Roentgenium atoms have 111 electrons and the shell structure is 2.8.18.32.32.18.1. The ground state electron configuration of ground state gaseous neutral roentgenium is [ Rn ]. 5f14.
