Diamond and graphite are two allotropes of carbon: pure forms of the same element that differ in crystalline structure.. Allotropy or allotropism (from Ancient Greek ἄλλος (allos) 'other' and τρόπος (tropos) 'manner, form') is the property of some chemical elements to exist in two or more different forms, in the same physical state, known as allotropes of the elements.
Peculiarly, above 1,394 °C (2,541 °F), iron changes back into the bcc structure, known as δ-Fe. [ 14 ] δ-iron can dissolve as much as 0.08% of carbon by mass at 1,475 °C. It is stable up to its melting point of 1,538 °C (2,800 °F). δ-Fe cannot exist above 5.2 GPa, with austenite instead transitioning directly to a molten phase at these ...
Phase information is based on the work of G. C. Vezzoli, et al., as reviewed by David Young; as Young notes, "The literature on the allotropy of sulfur presents the most complex and confused situation of all the elements." [8] [9] Phase information are limited to ≤50 kbar and thus omitting metallic phases. [10]
Carbon is capable of forming many allotropes (structurally different forms of the same element) due to its valency (tetravalent).Well-known forms of carbon include diamond and graphite.
For pure chemical elements, polymorphism is known as allotropy. For example, diamond, graphite, ... (changes from one state of matter to another) it usually either ...

Atomic oxygen, denoted O or O 1, is very reactive, as the individual atoms of oxygen tend to quickly bond with nearby molecules.Its lowest-energy electronic state is a spin triplet, designated by the term symbol 3 P.
