Is antimony Reactive or nonreactive?
Antimony and bismuth are relatively unreactive metals, but form compounds with oxygen and the halogens in which their oxidation states are +3 and +5 (as in Bi 2O 3 and SbF 5).
Is antimony stable or unstable?
Antimony is stable in air at room temperature, but reacts with oxygen if heated to produce antimony trioxide, Sb2O3. Antimony is a silvery, lustrous gray metalloid with a Mohs scale hardness of 3, which is too soft to make hard objects.
What is the reaction of antimony?
When heated antimony will react with oxygen in air for form antimony(III) trioxide. Antimony reacts under controlled conditions with all of the halogens to form antimony(III) dihalides. Antimony dissolves in hot concentrated sulphuric acid or nitric acid, to form solutions containing Sb(III).
Does antimony react with metals?
Metallic antimony is not affected by air or moisture under ordinary conditions, but it is gradually converted to an oxide if the air is moist. It can act as an oxidizing agent and reacts with many metals to form antimonides that, in general, resemble nitrides, phosphides, and arsenides but are somewhat more metallic.
What type of element is antimony?
semi-metal
Antimony is a semi-metal. In its metallic form it is silvery, hard and brittle. Antimony is used in the electronics industry to make some semiconductor devices, such as infrared detectors and diodes.
How do you identify antimony?
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).

What properties does antimony have?
Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle; the non metallic form is a grey powder. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis.
What elements does antimony react with?
Characteristics: Antimony is brittle and silvery. Not very active, but reacts with oxygen, sulfur and chlorine at high temperatures.
What is unique about antimony?
Antimony (Sb) has an atomic number of fifty-one, with fifty-one protons in the nucleus. It is a highly brittle, bluish-white, semi-metallic element. Interesting Antimony Facts: Its name is attributed to the French word for “monk killer,” since toxic antimony is linked to alchemy, which was often studied by monks.
Is antimony a conductor or insulator?
Antimony is a brittle metal and is a poor conductor of heat and electricity. Very pure antimony is used to make certain types of semiconductor devices, such as diodes and infrared detectors.

What are the sources of antimony?
Sources. Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite (antimony sulfide) and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite, tetrahedrite and ullmannite. It is mined in China, Bolivia , South Africa and Mexico.
What element is antimony?
Antimony is a naturally existing chemical element. Native antimony from Mexico. Antimony is a shiny gray metalloid which exists in nature as sulfide mineral stibnite. The atomic number of antimony is 51, and its chemical symbol is Sb, which is derived from the Latin term “stibium.”.
What is the history of antimony?
The metal antimony was known to German chemist Andreas Libavius in 1615 who obtained it by adding iron to a molten mixture of antimony sulfide, salt and potassium tartrate . This procedure produced antimony with a crystalline or starred surface.
What is the formula for antimony sulfide?
Antimony trisulfide, also known as antimony(III) sulfide, is a chemical compound. Its chemical formula is Sb 2S 3. It has antimony and sulfide ions in it. The antimony is in its +3 oxidation state.
