WebThe structure of a bismuth crystal is just so wild and the beautiful color that happens when it oxidizes is captivating. When metal oxidizes, it means that its outer layer has changed because of its exposure to the oxygen in the air around us. When iron oxidizes, it gets a red-orange colored layer we call rust.

Physical characteristics Bismuth is a brittle metal with a dark, silver-pink hue, often with an iridescent oxide tarnish showing many colors from yellow to blue. The spiral, stair-stepped structure of bismuth crystals is the result of a higher growth rate around the outside edges than on the inside edges. The variations … See more Bismuth is a chemical element with the symbol Bi and atomic number 83. It is a post-transition metal and one of the pnictogens, with chemical properties resembling its lighter group 15 siblings arsenic See more Bismuth forms trivalent and pentavalent compounds, the trivalent ones being more common. Many of its chemical properties are similar to those of arsenic and antimony, although they are less toxic than derivatives of those lighter elements. Oxides and sulfides See more Bismuth has few commercial applications, and those applications that use it generally require small quantities relative to other raw materials.
