What is the transformation between allotropes

Allotropic.

It refers to a single element composed of the same single chemical element, but with different properties. The differences in properties between allotropes are mainly manifested in physical properties, and there are also differences in activity in chemical properties. For example, the two allotropes of phosphorus, red phosphorus and white phosphorus, have ignition points of 240 and 40 degrees Celsius respectively, and the products after full combustion are phosphorus pentoxide; White phosphorus (P

It is highly toxic and soluble in carbon disulfide, and red phosphorus (P) is non-toxic, but insoluble in carbon disulfide. Allotropes can convert into each other under certain conditions, and this transformation is a chemical change.

The most common allotropes of carbon in life: graphite, diamond, and C-60 (also known as Fu, or Buck ball); There are also allotropic forms of phosphorus: white phosphorus and red phosphorus; In addition, ozone and oxygen are also two allotropes of the element oxygen.

To put it simply, allotropes are: the same element has different physical properties and chemical properties due to different arrangements.

Allotropes are objects made of the same elements and in different forms.

Allotropes have different physical properties due to different structures; But because it is formed by the same element, the chemical properties are similar.

For example, oxygen is a colorless and odorless gas, while ozone is a light blue gas with a fishy smell. The boiling point of oxygen is -183, while the boiling point of ozone is -111 5; Oxygen is more stable than ozone, and it is not as oxidizing as ozone. It must be elemental. For example, oxygen and ozone, one is O2 and the other is O3

Diamond and graphite, both carbon.

Under certain conditions, allotropes can be converted into each other, and this transformation requires a chemical reaction to complete.

Allotropes are formed in three ways:

1 The number of atoms that make up the molecule is different, e.g. oxygen O2 and ozone O32 The arrangement of atoms in the lattice is different, e.g. diamond and graphite.

3 The arrangement of molecules in the crystal lattice is different, e.g. orthogonal sulfur and monoclinic sulfur.

In addition, ozone and oxygen are also oxygen elements.

of the two allotropic forms. To put it simply, allotropes are: the same element produces different physical and chemical properties due to different ways of removing dust.

Nature characteristics. Allotropes have similar chemical properties. In the well-known example of diamond and graphite, each carbon atom of diamond is covalently bonded with four adjacent carbon atoms.

joined, forming a tetrahedral structure, which is a type of atomic crystal.

In graphite, the carbon atoms are arranged in layers, and the carbon atoms in each layer are connected by covalent bonds to form a planar hexagon, so it is relatively stable, but the layers only rely on weak intermolecular forces.

connection, which is prone to relative sliding, so the chemical properties of graphite are more active than those of diamond, and the difference in physical properties is more obvious.

Diamond is a colorless and transparent crystal with a melting point and hardness much greater than graphite. Graphite, on the other hand, is a dark gray, soft, opaque, and easily conductive flake-like solid.
