Question

Diamond and graphite are both polymorphs of ________

Answer 1

Answer: The correct answer for the blank is -

Carbon.

Step-by-step explanation:

Polymorphs can be described as two or more minerals that have the same chemical composition or made up of same chemical but have difference in their atomic arrangement and crystalline structure.

Example- Diamond and Graphite both are the crystalline form of carbon as both are formed of pure carbon.

In Diamond, the atoms are packed with one another and also linked to several other carbon atoms as compared to Graphite, where there are weak bonds between the layers.

Answer 2

Diamond and graphite are both polymorphs of carbon. Polymorphism or allotrophy involves the existence of an element in more than one crystalline form, but similar physical state. An example of polymorphism is of carbon. The element carbon can exist in many forms, two such forms are graphite and diamond. Diamond can be converted into graphite, at a phase change point or transition point.
