allotropies meaning in Hindi

Examples

1. For pure chemical elements, polymorphism is known as allotropy.
2. Iron represents perhaps the best-known example for allotropy in a metal.
3. By 1912, polymorphism known for compounds, and proposed that the terms allotrope and allotropy be abandoned and replaced by polymorph and polymorphism.
4. The base metal iron of the iron-carbon alloy known as steel, undergoes a change in the arrangement ( allotropy ) of the atoms of its crystal matrix at a certain temperature ( usually between and, depending on carbon content ).
5. "' Allotropy "'or "'allotropism "'( ) is the property of some chemical elements to exist in two or more different forms, in the same physical phase ( i . e . different solid, liquid or gas forms ); these different states are not, themselves, considered to be examples of allotropy.
6. "' Allotropy "'or "'allotropism "'( ) is the property of some chemical elements to exist in two or more different forms, in the same physical phase ( i . e . different solid, liquid or gas forms ); these different states are not, themselves, considered to be examples of allotropy.
7. *Allotropy also makes the point of elements having multiple oxidation states ( many workable arrangements of electrons ) and variable co-ordination numbers ( many workable arrangements of neighbouring atoms ) ( both apply to carbon ) having more allotropes . and there are other elements with large amounts of allotropes too, eg . black, white and red phosphorus for example; oxygen, ozone and tetraoxygen, and sulfur has even more than carbon.
