What are the allotropes of antimony?
Antimony is resistant to attack by acids. 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.
What are the 3 allotropes of sulfur?
List of allotropes and forms
| Formula/name | Common name |
|---|---|
| S2 | disulfur |
| S3 | trisulfur |
| S4 | tetrasulfur |
| cyclo-S5 | cyclo-pentasulfur |
How many allotropes of antimony are there?
four allotropes
A metalloid, rather than a true metal, antimony exists in four allotropes: the most stable is metallic and grey; with a non-metallic yellow, a black and an explosive white form also known.
What are the allotropes of sulfur?
The Allotropes of Sulphur yellow rhombic sulphur (α-sulphur) and the monoclinic (β-sulphur). The most interesting feature is their thermal stability, the allotropes of sulphur are inter-convertible i.e. rhombic sulphur when heated above 369K gives monoclinic sulphur. Let us discuss these two allotropes in detail.

What is the texture of antimony?
Metallic antimony is an extremely brittle metal of a flaky, crystalline texture. It is bluish white and has a metallic lustre. It is not acted on by air at room temperature, but burns brilliantly when heated with the formation of white fumes. It is a poor conductor of heat and electricity.
What is allotropy give two examples of allotropes of sulphur?
⋅ Rhombic sulphur, monoclinic sulphur and plastic sulphur are allotropic forms of sulphur.
Which of the following are Peroxoacids of sulphur?
Peroxocids of sulphur are H2S2O8 and H2SO5.

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 type of solid is sulphur?
Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water. It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements.
What is antimony trichloride formula?
SbCl3Antimony trichloride / Formula
CAMEO Chemicals. Antimony trichloride is an inorganic chloride salt with formula SbCl3. It is used as a reagent for detecting vitamin A and related carotenoids, reacting with the carotenoid to form a blue complex that can be measured by colorimetry (the Carr-Price test).
