WebGold. Gold is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal. Gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold is thought to have been produced in supernova nucleosynthesis, from the collision of neutron stars. WebGold is highly reflective of heat and light. The visors of astronauts' space helmets receive a coating of gold so thin (0.00005 millimeters, or 0.000002 inches) that it is partially …
