Question

The different physical forms of the same element in the same physical state are called

Answer 1

• The phenomenon of existence of an element in two or more different physical forms is called allotrophy.
• The different physical forms of the same element in the same physical state are called allotropes.
• The elemental $\mathrm{Carbon}\left(\mathrm{C}\right)$ show the property of allotropy.
• There exist in 2 different forms which are crystalline form and amorphous form.
• The crystalline form of $\mathrm{Carbon}\left(\mathrm{C}\right)$ has a regular and definite arrangement of atoms.
• Graphite and diamonds are the crystalline form of $\mathrm{Carbon}\left(\mathrm{C}\right)$.
• In the amorphous form of $\mathrm{Carbon}\left(\mathrm{C}\right)$ there is an irregularity in the arrangement of atoms.
• Charcoal, Carbon black,Coal and lampblack are examples of amorphous carbon.

Thus, The different physical forms of the same element in the same physical state are called allotropes
