What is antimony physical properties?
Physical properties 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).
What is antimony science?
Antimony is a lustrous silvery bluish white solid that is very brittle and has a flaky texture. It occurs chiefly as the gray sulfide mineral stibnite (Sb2S3). stibnite. Stibnite, the primary mineral from which antimony is obtained.
What is antimony in geography?
Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb2S3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.
Who founded antimony?
Nicolas Lémery, a French chemist, was the first person to scientifically study antimony and its compounds. He published his findings in 1707.
What is antimony and its uses?
Antimony is a semi-metal. In its metallic form it is silvery, hard and brittle. Uses. Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes. It is alloyed with lead or other metals to improve their hardness and strength.
What are the type antimony?
Four allotropes of antimony are known: a stable metallic form, and three metastable forms (explosive, black, and yellow). Elemental antimony is a brittle, silver-white, shiny metalloid. When slowly cooled, molten antimony crystallizes into a trigonal cell, isomorphic with the gray allotrope of arsenic.
What is the origin of antimony?
Word origin: Antimony was named after the Greek words anti and monos to mean “a metal not found alone.” The chemical symbol, Sb, comes from the element’s historical name, stibium. Discovery: Antimony was a known metal in the 17th century and was likely used even earlier.

How do you identify antimony?
- Antimony is a silvery-white metal that is found in the earth’s crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide.
- Antimony powder appears as a silvery or gray solid in the form of dust.
- Antimony(0) is an elemental antimony.
What is the history of antimony?
Who studied antimony?
Nicolas Lémery
Nicolas Lémery, a French chemist, was the first person to scientifically study antimony and its compounds. He published his findings in 1707. Antimony makes up about 0.00002% of the earth’s crust.
What is antimony an example of?
Classified as a metalloid, you can spot antimony on the periodic table next to metalloid neighbors arsenic (As) and tellurium (Te). A metalloid is a chemical element that has a mixture of properties between a metal and nonmetal.
What is another word of antimony?
In this page you can discover 17 synonyms, antonyms, idiomatic expressions, and related words for antimony, like: vanadium, sb, bismuth, thallium, osmium, periodic-table, atomic number 51, tellurium, manganese, strontium and yttrium.
What was antimony first used for?
In the mid-17th century, antimony was first added as a hardening agent to pewter (an alloy of lead and tin).
How is antimony made?
Some antimony is produced as a by-product of smelting ores of other metals, mainly gold, copper and silver, in countries such as the United States, Canada, and Australia. Important amounts of antimony are yielded as a by-product of copper and silver mining. Numerous stibnite deposits occur in Idaho, Montana and Nevada.
What are the properties of terbium?
Terbium is a soft, malleable, ductile, silver-gray metal member of the lanthanide group of the periodic table. It is reasonably stable in air, but it is slowly oxidised and it reacts with cold water. Terbium is rare and expensive, so it has few commercial uses.
What is the Latin origin of antimony?
Origin of name : from the Greek words “anti + monos” meaning “not alone” (the origin of the symbol Sb comes from the Latin word “stibium”).
What does antinomy mean in philosophy?
In philosophy, the word antinomy is used to designate the conflict of two laws that are mutually exclusive or that oppose one another. When two carefully drawn, logical conclusions contradict each other, the result is antinomy. A simple example of antinomy is the statement “This sentence is false.” The basic statement…
What is antimony?
Antimony is a silvery, lustrous gray metalloid with a Mohs scale hardness of 3, which is too soft to make hard objects; coins of antimony were issued in China’s Guizhou province in 1931 but the durability was poor and the minting was soon discontinued.
What is the stability of antimony at 100 degrees Celsius?
At 100 °C, it gradually transforms into the stable form. The yellow allotrope of antimony is the most unstable; it has been generated only by oxidation of stibine (SbH 3) at −90 °C.
What is the gas phase of antimony pentoxide?
In the gas phase, the molecule of the compound is Sb 4O 6, but it polymerizes upon condensing. Antimony pentoxide ( Sb 4O 10) can be formed only by oxidation with concentrated nitric acid. Antimony also forms a mixed-valence oxide, antimony tetroxide ( Sb 2O 4 ), which features both Sb (III) and Sb (V).
