| Also Known As | Allotropes; allotropy; allotropic forms; polymorphic forms (for elements); crystal modifications |
What is Allotropic Modifications (Allotropes)?
Allotropic modifications refer to the different physical forms in which an element can exist in the same state of matter, each having distinct physical properties but the same chemical composition. They arise from different bonding arrangements or crystal structures. Common examples include diamond and graphite (carbon), rhombic and monoclinic sulfur, red and white phosphorus.

See Allotropes entry — applications vary by specific allotropic form
Varies by element — white phosphorus is highly toxic and pyrophoric; ozone is irritating; other allotropes are generally safer.
