Editing Allotropy (section)

==Differences in properties of an element's allotropes==
Allotropes are different structural forms of the same element and can exhibit quite different physical properties and chemical behaviours. The change between allotropic forms is triggered by the same forces that affect other structures, i.e., [[pressure]], [[photochemistry|light]], and [[temperature]]. Therefore, the stability of the particular allotropes depends on particular conditions. For instance, [[iron]]  changes from a [[body-centered cubic]] structure ([[Allotropes of iron|ferrite]]) to a [[face-centered cubic]] structure ([[austenite]]) above 906&nbsp;°C, and [[tin]] undergoes a modification known as [[tin pest]] from a [[metal]]lic form to a [[semimetal]]lic form below 13.2&nbsp;°C (55.8&nbsp;°F). As an example of allotropes having different chemical behaviour, ozone (O<sub>3</sub>) is a much stronger oxidizing agent than dioxygen (O<sub>2</sub>).
