Question

Charcoal is ______ (a crystalline/an amorphous) form of carbon.

Answer 1

Allotropy:

• The ability of an element to exist in more than one physical forms having same physical state is called as allotropy.
• The various existing forms having same physical state, exhibiting identical chemical properties but different physical properties
  are called as allotropic forms.
• Carbon shows two major types of allotropic forms; crystalline and amorphous forms.
• For example; Diamond and Graphite are the allotropic forms of carbon.

Amorphous forms of carbon:

There are different types of amorphous forms of carbon like coal, lampblack, charcoal, gas carbon and coke.

Thus, Charcoal is an amorphous form of carbon.
