Examples of Molecules
Molecules
It is a set or group that contains sufficiently stable and neutral electrical form, composed of at least two atoms joined through strong chemical bonds, composed in a well-defined configuration.
They represent the smallest particle that can exist within a substance either in its physical and chemical properties, in turn they are made up of two atoms or in some cases more than two. Molecules are in constant motion and the union of their atoms occurs thanks to the exchange of electrons. One of the main characteristics they have is that they can carry an electric or neutral charge.
The term molecule can vary depending on the area where it is used, although its base structure is always the same. In the area of biochemistry as well as in organic chemistry , the term molecule is used less strictly, being applied in the same way both in biomolecules and in organic compounds.
Molecules can be classified into two types, namely:
-
- The discreet
These are characterized by being made up of a certain number of atoms of the same or different element.
- Macromolecules
They are those that are made up of a large number of atoms and that these in turn have a simple structure. In this second case, living organisms have a large number of macromolecules that as structural matter.
The organic chemistry is the branch that specializes in the study of molecules containing carbon and which result in covalent bonds such as carbon-carbon or carbon-hydrogen better known by the name of organic compounds.
