==Key Stage 4==
===Meaning===
[[Allotrope]]s are different arrangements of [[atom]]s in an [[element]].
===About Allotropes===
: Different [[allotrope]]s of the same [[element]] can have very different [[Physical Property|physical properties]] such as [[Melting Point|melting point]] and [[Electrical Conductivity|electrical conductivity]].
===Examples===
These are several [[allotrope]]s of [[Carbon]].
