To date, 118 chemical elements have been found. Professor Mario Markus, Max Planck Institute for Molecular Physiology, Dortmund, Germany, takes a look at each element, presenting a poem based on its natural properties along with a scientific overview of each element.
All 118 poems – as well as some poems about elements that only exist in theoretical simulations – are published in the book Chemical Poems: One On Each Element by Mario Markus. ChemViews Magazine publishes a selection of these poems.
Reddish-white metal. Density: 9.78 g/cm³. It was discovered around 1400 by an unknown alchemist. The name comes from old German Bisemutum, meaning “white mass”, which is a mineral now known to be bismuth oxychloride. In air, the surface of bismuth is covered with a yellow and blue iridescent sheen, due to the formation of a layer of oxide. Bismuth was incorporated by the Incas in bronze-like alloys , which were used for making knives.
Bismuth oxychloride is utilized for the “pearl effect” in cosmetics and cheap jewelry. Bismuth subgallate (“Devrom”) serves as “internal deodorant” neutralizing the odor of passed gas . Other compounds are used to treat lupus erythematodes, which is an autoimmune disease, as well as against ulcers, asthma and syphilis . The treatment with bismuth compounds may cause a dark ridge on the gums, due to bismuth sulfide deposits.
During solidification (the solid floating on the liquid state, analogously to ice on water) impressive crystals occur, having the shape of square spirals with steps, reminiscent of Mayan temples with a touch of science fiction .
