Explanation

The different allotropic forms of sulphur arises partyl from the extent of which S has plymerised and partly the crystal structures adopted.
The two common crystalline forms are `alpha` or rhomibc sulphur and `beta` or monoclinic sulphur. A third modification is `gamma`monocloinic sulphur. All three forms contains puckered `S_(8)` rings with a crown conformation
Engeels sulphur (`epsi`- sulphur) containing `S_(6)` rings. `S_(7) . S_(9), S_(11), S_(12), S_(18) and S_(20)` rings have been made by Schamidt and his group.
Plastic or `gamma` sulphur contains spiral chains and sometimes `S_(8) ` and other rings.
The order allotropic forms of sulphur are milk of sulphur and colloidal or `delta` sulphur.
