Explanation:

$\huge\underbrace\mathtt\red{☆ALLOTROPHES☆}$

☞Different physical forms of an element having same chemical properties but different physical properties are called allothrophes.

$\huge\underbrace\mathtt{Allothrophes Of Carbon}$

$\huge\underline\mathtt\blue{1. Diamond}$

☞In diamond, each carbon atom is attached to four carbon atoms by strong single covalent bonds in the form of a regular tetrahedron.

$\huge\underline\mathtt\green{2. Graphite}$

☞Graphite is a greyish black substance which occurs in the earth's crust in free state but it can also be prepared artificially from carbon in an electric furnace at 2273-2773K. Its melting point is 4300K.

$\huge\underline\mathtt\purple{3. Fullerene}$

☞Fullorene is a dark solid at room temperature. It's a giant molecule containing thousands of carbon atoms, C60 Fullorene is a very small molecule containing only 60 carbon atoms.

Answer 2

Allotropes:

★ Allotropes are different forms of the same element. Different bonding arrangements between atoms result in different structures with different chemical and physical properties.

Allotropes of carbon:

1.) Graphite:

It is a soft, black, flaky solid, a moderate electrical conductor. The C atoms are bonded in flat hexagonal lattices (graphene), which are then layered in sheets.

2.) Diamond:

It is extremely hard, transparent crystal, with the carbon atoms arranged in a tetrahedral lattice. This allotrope of carbon is a poor electrical conductor and an excellent thermal conductor.

3.) Fullerenes:

Fullerene molecules are composed entirely of carbon, in form of a hollow sphere, ellipsoid or tube. An example is Buckminsterfullerene that is made of 60 carbon atoms.
