they are all pure carbon, so their formulae are the same, but their chemical structure is different,

Graphite
--------------------------------------------------------------------------------
Chemical Formula : C
Hardness : 1-2
Cleavage : One; perfect and easy
Luster : Metallic to dull
Color : Black to gray
Streak : Black
Density : 2.09-2.23
Diagnostic Features and Trivia : Graphite's low hardness and ease of cleavage is what makes it so useful as penicil lead. Various methods of pressure treating allow for varying bond strength which alters the hardness and therefore darkness of the "lead."
Crystal System and Habit : Hexagonal; uncommon - tabular
Twinning : None
Polymorphs : Diamond
Index of Refraction : Opaque
__________________________________________________

Carbon 100.00 % C
______
100.00 %
Empirical Formula: C
Environment: Gas rich, ultra-basic diatremes from mantle depths (>30 km)and alluvial placer deposits derived from the Kimberlite rocks. Kimberlite = olivine, garnet, pyroxene, and calcite.
IMA Status: Valid Species (Pre-IMA) Prehistoric
Locality: Kimberly, republic of South Africa. India. Brazil. Ural Mountains, Russia. Murfreesboro, Arkansas, USA. Link to MinDat.org Location Data.
Name Origin: From the Greek, adamas, meaning "invincible" or "hardest."
Synonym: Boart
Booart
Carbonado

As far as Amorphous goes.. what kind because amorphous by itself is any substance lacking a crystaline structure...
Hope that helps!

The chemical formula is just C but its relate to the topology and how they get together I mean the carbon lattice can see their structures on

take half a kilo of grapes, add bread and 250 gms of boot-polish. Stir hard....... and there you have it!!!
By the way, what does your question mean?

all are carbon. it's just the structure that's different
