Question

8. Diamond and graphite show different physical properties although they are made up of carbon and

shows same chemical properties. What is the property called?​

Answer 1

Answer:

This property called Allotropy or allotropism this is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements.

Allotropes are different structural modifications of an element; the atoms of the element are bonded together in a different manner.  

Diamond and Graphite, are well-known allotropes of carbon.

Answer 2

Answer:

Diamond and Graphite are both composed of Carbon. The only difference is that their structures and arrangement in space lattice is different! They both are allotropes of Carbons. Hence, the property is called Allotropy.

Explanation:

Graphite: It has a hexagonal sheet like structure and these sheets are stacked one over the other that can slide over each other. It is due to this reason graphite is slippery. Also, presence of an unpaired electron makes Graphite an excellent conductor.

Diamond: It has a tetrahedral structure and no free electrons. This makes Diamond extremely hard and a poor conductor of electricity.

See, both are composed of carbon yet one is so precious and loved whilst the another is not.
