[Edit this paragraph] element name

The Latin name of antimony and the element symbol Sb both come from the English name stinite of antimony. The original meaning of this word is "anti-monk". It is said that many monks in ancient western countries suffered from leprosy, and they tried to take stibnite containing antimony to treat it. However, many monks who took stibnite did not recover, but their condition deteriorated and they died one by one.

[Edit this paragraph] element description

The content of antimony [1] in the crust is 0.000 1%, which mainly exists in the form of simple substance or stibnite, galena, stibnite and antimony ochre. At present, there are as many as 120 kinds of antimony-containing minerals known. Antimony is hard and brittle, and antimony tungsten ore is easily broken, shiny, malleable and malleable. There are three allotropes of antimony: yellow antimony, gray antimony and black antimony. Antimony is silvery white, brittle and has unique thermal shrinkage and cold expansion. Amorphous antimony is gray and can be prepared by electrolytic antimony halide.

Antimony has two allotropes: the yellow variant is only stable below MINUS 90 degrees Celsius; Metal variants are stable forms of antimony. Antimony vapor is a monoatomic molecule at 2070℃.

Antimony is not a very active element. It only reacts with water in red heat to release hydrogen, which will not be oxidized by air at room temperature, but can be combined with fluorine, chlorine and bromine. When heated, it can only be combined with more than 100 metals such as iodine. Antimony is easily soluble in hot nitric acid to form hydrated antimony oxide. It can react with hot sulfur to produce antimony sulfate. Antimony can react with oxygen at high temperature to produce antimony trioxide, which is an amphoteric oxide, insoluble in water, but soluble in acid and alkali. It can react with concentrated nitric acid.
