The element undergoes decay under spontaneous fission process. Certain Facts About 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.

Basic Nuclear Properties 3 Roentgenium - Atomic Number - Atomic Mass - Density of Roentgenium . This article summarizes key chemical and thermal properties of this chemical element and atom. Further data for naturally occuring isotopes of roentgenium are listed above. This table gives information about some radiosotopes of roentgenium, their masses, their half-lives, their modes of decay, their nuclear spins, and their nuclear magnetic moments. Isotope Mass / Da Half-life Mode of decay Nuclear spin Nuclear magnetic moment; 272 Rg Roentgenium (111Rg) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no stable isotopes.

Roentgenium exists in solid form under normal conditions. It crystallizes in a cubic structure that has a body-centered symmetry. Roentgenium is thought to be a very dense metal and would have a density of round 28.7 g/cm 3. But due to its unstable nature, the physical properties can only be predicted or theoretically calculated.
