What are the different elements of the same element?
The same element forms the same element is the same shape, the most common life, there are carbon allotrope: graphite, diamond and C-60 (also known as Fu, or Buck ball); and phosphorus with the same Essential bodies: white phosphorus and red phosphorus; In addition, ozone and oxygen are two elements of the same element of oxygen.
The same kind of elements are pure substances, such as: oxygen, hydrogen. Different elements can also form a pure substance, such as: carbon monoxide, carbon dioxide (water is a mixture of) It depends on the situation, the same element can be composed of different elements, : Oxygen and ozone, one is two oxygen atoms, one is three oxygen atoms.
The same type of body, refers to the same single chemical elements, but the nature is not the same element. The difference in the nature of the allotropes is mainly manifested in the physical properties, chemical properties also have a difference in activity. Such as phosphorus, two kinds of allotropes, red phosphorus and white phosphorus, their ignition points are 240 and 40 degrees Celsius, after the full combustion of the product are phosphorus pentoxide; white phosphorus (P4) is highly toxic, soluble in carbon disulfide, Red phosphorus (Pn) is non-toxic but insoluble in carbon disulfide. Allotropes can be transformed from each other under certain conditions, and this transformation is a chemical change.
