Introduction
Carbon lies on group 14 or IVA and 2nd period in the periodic table.
It is a p-block element.
Elements of group 14 are carbon (C), silicon (Si), germanium (Ge), tin (Sn) a
(Pb).
Allotropes of carbon:
The same element can exist in different physical forms and the different p
forms of the same element are called allotropes.
The phenomenon of existence of different allotropes of an element is
allotropism.
The existence of allotropes of any element is due to different bond
corresponding state.
The allotropes have different physical properties and to some extent same ch
properties

Crystalline solid
In crystalline solids the particles are arranged in a 3-dimensional orde
has regular shape) . The particles have equal intermolecular forces. They have
melting point.
Amorphous solid
Amorphous means shapeless. It has irregular arrangement of solid pa
The intermolecular forces are not equal. Also, the distance between particles
They have undefined geometric shape.
