electron dot structure of a molecule of sulphur made up of eight atoms of sulphur?

On heating sulphur, till almost the boiling point and suddenly cooling it by pouring into cold water a viscous mass is formed. This sudden cooling does not allow sufficient time to the molecules to rearrange themselves to form monoclinic or rhombic forms of sulphur. He..

A chemical element is said to exhibit allotropy when it occurs in two or more free forms in the same physical state; the forms are called allotropes. Allotropes generally differ in physical properties such as color and hardness; they may also differ in molecular structure or chemical act..

. Examples: CO 2 , H 2 O, SO 3 , HCl Depending upon the number of atoms in one molecule of the element it can be classified a..

(i) It is a most stable and common form of sulphur. (ii) It is also called a -Sulphur. (iii) It has bright yellow colour. (iv) It is insoluble in water and carbon disulphide. (v) Its density is 2.07 g cm - 3 . (vi) It exists as S 8 molecule. The eigh..

The shapes of rhombic and monoclinic sulphur are different because of the difference in the packing of molecules. Those both contain S 8 rings and the molecules are stacked differently as shown in the figure abov..

The number of atoms, which constitute one molecule of an element, is called its atomicity. Phosphorus: P 4 - 4 atomicity Sulphur: S 8 - 8 atomicity Oxygen: O 2 - 2 atomicity Recently a different form of carbon..

When heated, sulphur undergoes a series of characteristic changes. Sulphur can melt at two different temperatures. a) If heated rapidly, it melts at 112.8 o C. b) But if heated slowly it will melt only at 118.6 o C. Roll sulphur is rhombic. When heated it slo..

Heat on sulphur is a physical change. When heated, it undergoes a series of changes in colour, form and viscosity at various temp. 115 o C 115 - 180 o C Beyond 180 o C Straw coloured liquid E..

Two of the important oxides of sulphur are sulphur dioxide and sulphur trioxide. Sulphur dioxide is formed by burning sulphur in air or roasting metal sulphides in the presence of air. A large amount of SO 2 gas is released into the atmosphere from ..
