Allotropes Definition:
Different crystalline or molecular forms of the same element are called allotropes.
Cambridge International AS and A Level Chemistry by Ryan Lawrie, Roger Norris
Allotropes Notes:
The term allotrope stands for one or more forms of a chemical element that occur in the same physical state. The ways in which atoms are bonded in allotropes are different and that is why they exist in different forms. For example carbon has three allotropes, diamond, graphite and buckey ball. Allotropes of the same element have different chemical and physical properties. For example in case of allotropes of carbon, diamond is extremely hard and graphite is soft. In diamond, atoms are bonded to form a tetrahedral lattice while in graphite they are bonded to form sheets of a hexagonal lattice. Another example is of Phosphorus. It also has different allotropic forms and these allotropes display different colours such as red, yellow and white.
