Antimony is a silvery-white, shiny element that looks like a metal. It has a scaly surface and is hard and brittle like a non-metal. It can also be prepared as a black powder with a shiny brilliance to it. The melting point of antimony is 630°C (1,170°F) and its boiling point is 1,635°C (2,980°F).
Properties and reactions. The most stable form of elemental antimony is a brittle silvery solid of high metallic luster. Electrolytic deposition of antimony under certain conditions produces an unstable amorphous form called “explosive antimony,” because, when bent or scratched, it will change in a mildly explosive manner to the more stable ...
What is Antimony. Antimony (pronunciation: AN-te-MOH-nee) is a lustrous metallic element that belongs to the family of metalloids and is represented by the chemical symbol Sb [1, 2, 3]. There are two stable isotopes of antimony, including 121 Sb and 123 Sb with a natural abundance of 57.21% and 42.79% respectively [4].
Jul 28, 2019 · Updated on July 28, 2019. Antimony (atomic number 51) compounds have been known since ancient time. The metal has been known since at least the 17th century. Electron Configuration: [Kr] 5s 2 4d 10 5p 3. Word Origin. Greek anti - plus monos, meaning a metal not found alone. The symbol comes from the mineral stibnite. Properties.
antimony , Semimetallic to metallic chemical element (see metal), chemical symbol Sb, atomic number 51. Of its various allotropes, the most common is a lustrous, bluish, brittle, flaky solid. In nature antimony occurs chiefly as the gray sulfide mineral stibnite, Sb 2 S 3.
Dec 17, 2014 · Antimony is poisonous by inhalation and ingestion, and it has also been found to be carcinogenic 1, although the exact mechanisms of its toxicity are still unclear. This, however, hasn't...
