Like many other non-metals, sulphur also exhibits the phenomenon of allotropy. Various allotropic forms of sulphur are: rhombic sulphur, monoclinic sulphur and plastic sulphur. Some of their characteristics are given belo..

Sulphur is the second member of the oxygen family, yet it differs from oxygen in many respects. For e.g., O 2 exists as molecule while S 2 molecule does not. The difference in the chemical behavior of S and O arises due to following reasons. (i) Oxygen has a small size (73 pm) as compared..

Allotropy and Allotropes of Carbon - The existence of an element in more than one form, in the same physical state, is called allotropy. The various forms are called allotropes. Allotropy is the result of different arrangement of the atoms in the crystal structure of the element..

The existence of an element in more than one form, in the same physical state, is called allotropy. The various forms are called allotropes. Allotropy is the result of different arrangement of the atoms in the crystal structure of the element. As a result, the allotropes e..

Rhombic sulphur is prepared by dissolving roll sulphur in carbon disulphide, and then evaporating the solution slowly, at room temperature. Eight sided crystals of rhombic sulphur crystallise out (Fig.13.22..

This allotrope of sulphur is prepared by melting roll sulphur in a dish. The molten sulphur is allowed to cool slowly. The top layer solidifies first and forms a crust. Two holes are made in the crust with the help of a heated nail. The molten sulphur..
