Examples of Chemistry

We explain that what are examples of Chemistry The chemistry is the science that studies matter in all its aspects, comprising internal structure, their properties, their general behavior. In addition, it is responsible for describing how energy manifests itself during its transformations, when two or more different types of matter interact to become new substances.

It is one of the great disciplines that help to understand the world and the laws that govern it. Its basis of study are atoms , which are an arrangement made up of a nucleus with neutrons and protons compact together, and a certain number of electrons. orbiting around the nucleus. The atom is the fundamental piece so that a multitude of substances are formed.

When matter has only one type of atoms , then it is a pure substance called a chemical element, which will behave identically in all its portions and combine in a specific way with other elements, forming chemical compounds. The latter, as new matter, have as their basic unit the molecule , a union of the elements.

Periodic table of the chemical elements

The Russian chemist Dmitri Mendeleev consolidated in the 19th century the definitive register of chemical elements, a table organized by columns to indicate those with similar properties and which at the same time, in an advance from left to right, showed the atomic number (number of protons in the nucleus) in ascending order. This table, definitely called the Periodic Table of Chemical Elements , is the primary tool of every professional chemistry.

Chemistry types

According to the type of matter that you study, chemistry is going to be classified into two main branches:

  • Inorganic chemistry
  • Organic chemistry

Inorganic chemistry

The inorganic chemistry is the branch of chemistry that studies the mineral substances that make up the earth ‘s crust and seawater. These are very varied and can contain the atoms of any element in the periodic table. The chemical compounds that are described in it are very abundant and result from the numerous combinations of the elements.

Organic chemistry

The organic chemistry is the branch of chemistry studying substances are mainly constituted by chains of carbon atoms, supplemented with hydrogen and other elements such as oxygen, nitrogen, phosphorus, sulfur. Many of these molecules also participate in biological processes, so biochemistry is derived from organic chemistry .

The variety of organic compounds is much greater than that of inorganic compounds, since the same carbon chains can be branched in infinite ways and that gives them different properties. Therefore, in addition to biochemistry, other more specific branches arise according to their purpose: pharmaceutical, food, industrial, petrochemical, etc.

10 chemistry examples

The main branches of chemistry are listed below, dedicated to studying in depth each of its aspects:

  1. Biochemistry: Studies the substances that participate in metabolism and all the reaction mechanisms that help biological organisms function.
  2. Physicochemistry: Study the physical phenomena involved in chemical reactions, at an atomic and macroscopic level.
  3. Analytic chemistry: Analyze samples of matter, subjecting it to reaction with certain reagents and, based on the results, understand its composition.
  4. Inorganic chemistry: It is the one that studies the mineral substances that make up the earth’s crust and sea water.
  5. Organic chemistry: It is the one that studies biological substances and those derived from oil.
  6. Industrial Chemistry: Study and put into practice inorganic and organic chemistry, to produce useful materials for humanity and benefit the economy.
  7. Macromolecular Chemistry: Study the preparation, characterization, properties and applications of macromolecules or polymers.
  8. Neurochemistry: It is the study of chemical reactions that occur within the brain under the influence of neurotransmitters.
  9. Petrochemical: It studies the processes for obtaining and the composition of oil, made up mostly of hydrocarbons.
  10. Pharmaceutical chemistry: It studies the organic compounds that are capable of intervening in biological processes in order to cure diseases and improve health. You put this knowledge to use to develop and improve these products.
