What are the allotropes of phosphorus?
The two most common allotropes are white phosphorus and red phosphorus. Another form, scarlet phosphorus, is obtained by allowing a solution of white phosphorus in carbon disulfide to evaporate in sunlight.
What are the main allotropes of oxygen?
There are 4 known allotropes of oxygen:
- dioxygen, O2 – colorless.
- ozone, O3 – blue.
- tetraoxygen, O4 – red.
- metallic oxygen – obtained at very high pressures[1]
What are the 8 allotropes of carbon?
Allotropes of carbon
- Two familiar allotropes of carbon: graphite and diamond.
- Eight allotropes of carbon: (a) diamond, (b) graphite, (c) lonsdaleite, (d) C60 buckminsterfullerene, (e) C540, Fullerite (f) C70 Fullerene, (g) amorphous carbon, (h) zig-zag single-walled carbon nanotube.
What are allotropes of boron?
Allotropes of boron Under special circumstances, boron can form α-tetragonal, and γ-orthorhombic allotropes. Two amorphous forms, one a finely divided powder and the other a glassy solid, are also known and a further 14 allotropes have been reported.
What is Allotropy write any two allotropes of phosphorus?
The main allotropes of phosphorus include the white phosphorus, red phosphorus and black phosphorus. In addition to these, there also exists a violet phosphorus. However, that is not a significant allotrope.
What is Allotropy and allotropes of carbon?
When an element exists in more than one crystalline form, those forms are called allotropes; the two most common allotropes of carbon are diamond and graphite. Every carbon atom is covalently bonded at the four corners of the tetrahedron to four other carbon atoms.
Which of the following is an allotrope of carbon?
Coal, Graphite, Diamond and Coke are the allotropes of carbon.
What are the allotropes of sodium?
Allotrope Names of the elements
| Bromine | Dibromine |
|---|---|
| Lithium | None |
| Beryllium | None |

| Sodium | None |
What are the allotropes of carbon Class 10?
The three allotropes of carbon are:
- Diamond,
- Graphite, and.
- Buckminsterfullerene.
Which is an example of an allotrope of carbon?
The two or more forms of same element having similar chemical properties but different physical properties are called allotropes and the phenomenon is called allotropy. For example- diamond and graphite are two allotropes of carbon. Allotropes of carbon, sulphur and phosphorus are described below.
Are there any allotropes of the element phosphorus?
Allotropes of phosphorus Elemental phosphorus can exist in several allotropes, most commonly white, red and black. White phosphorus (P 4) exists as individual molecules made up of four atoms in a tetrahedral arrangement, resulting in very high ring strain and instability. White phosphorus is a yellow, waxy transparent solid.
Which is an allotrope of oxygen O 2 or O 3?
O 2 and ozone, O 3, are allotropes of oxygen. These allotropes persist in different phases, including the gas, liquid, and solid states. Phosphorus has several solid allotropes.
Why are some allotropes more stable than others?
The different physical properties displayed by allotropes of an element are explained by the fact that the atoms are arranged into molecules or crystals in different ways. Some allotropes of an element may be more chemically stable than others.
