Uranium - Howling Pixel

Uranium metal has a very high density of 19.1 g/cm 3, denser than lead (11.3 g/cm 3), but slightly less dense than tungsten and gold (19.3 g/cm 3). Uranium metal reacts with almost all non-metal elements (with the exception of the noble gases) and their compounds, with reactivity increasing with temperature.

Gold has only one stable isotope, 197 Au, which is also its only naturally occurring isotope, so gold is both a mononuclidic and monoisotopic element.Thirty-six radioisotopes have been synthesized, ranging in atomic mass from 169 to 205. The most stable of these is 195 Au with a half-life of 186.1 days. The least stable is 171 Au, which decays by proton emission with a half-life of 30 µs.

Gold - Howling Pixel

Gold is the most malleable of all metals. It can be drawn into a monoatomic wire, and then stretched about twice before it breaks. Such nanowires distort via formation, reorientation and migration of disloions and crystal twins without noticeable hardening. A single gram of gold can be beaten into a sheet of 1 square meter, and an avoirdupois ounce into 300 square feet.
