==Key Stage 3==
===Meaning===
[[Carbon]] is an [[element]] containing 6 [[proton]]s.
===About Carbon===
: [[Carbon]] is [[solid]] at [[Room Temperature|room temperature]].
: [[Carbon]] can form [[graphite]] or [[diamond]].
==Key Stage 4==
===Meaning===
[[Carbon]] is an [[element]] containing 6 [[proton]]s.
===About Carbon===
: The most common [[isotope]] of [[carbon]] is [[Carbon-12]] which has 6 [[proton]]s and 6 [[neutron]]s in the [[Atomic Nucleus|nucleus]].
: [[Carbon]] has 4 [[electron]]s in its [[Outer Shell|outer shell]] so it can form 4 [[bond]]s with other [[atom]]s.
: [[Carbon]] is able to make long chains of [[atom]]s to produce [[compound]]s called [[polymer]]s.
There are several [[allotrope]]s of [[Carbon]] including:
*[[Graphite]]
*[[Diamone]]
*[[Graphene]]
*[[Fullerenes]]
