Acid and chemical proof. However, tungsten rings are made out of jewelry grade tungsten which is safe to wear. Krypton is an element in gaseous state at NTP. It is usually used in many chemical and corrosive environments because carbides are typically chemically inert. Tungsten is a transition metal in the same block as many of the carcinogenic metals on the periodic table and holds potential to induce cancer-associated effects. Note that, these points are associated with the standard atmospheric pressure. Tungsten has an atomic number of 74, a relative atomic mass of 183.85, an atomic radius of 137 picometers, and a density of 19.35 grams per cubic centimeter. 6..
