Some examples of these substances are methane (CH 4 ) and acetic acid (CH 3 COOH). Among other utilities, organic chemistry allows the study and analysis of the molecular bases of living beings. Organic chemistry is one of the main branches of chemistry, from which the elements and chemical compounds that contain carbon (carbon-carbon or carbon-hydrogen bonds) are studied. Branches of chemistryĬhemistry is one of the most important sciences since its object of study is a matter, that is, everything that surrounds us in daily life.Ĭhemistry is a science that covers many areas of study that have generated different branches or classifications of chemistry studies.

Studies in chemistry are carried out in laboratories and employ the scientific method. This has allowed the discovery of various materials, their compositions, how they are related or transformed. Hence, elements that are basic in other scientific studies have been discovered. It is worth mentioning that matter is everything that surrounds us, composed of molecules and atoms that react to various chemical changes, and that can be related to the release of energy in some cases. The chemical element forms simple substances, for example, dioxide is a simple substance represented as O2 made up of two atoms of the element oxygen.Ĭhemistry is the science that studies matter, how it is composed, its properties and how its structures transform after undergoing various processes or reactions that affect its molecules and atoms. The chemical elements and their characteristics are summarized in what is called a periodic table of the elements . In the periodic table all the chemical elements are ordered in rows by their atomic number.Įach chemical element has an atomic symbol in addition to the atomic number, which is the abbreviation of the element.

three protons in its nucleus will be atom of the chemical element Lithium,Īnd so on with all the elements and Chemical Symbol.

two protons in its nucleus will be an atom of the chemical element Helium,.

a proton in its nucleus will be an atom of the chemical element Hydrogen,.

The atomic number determines the element, such as an atom with: The chemical element is a substance defined by a set of atoms that have the same number of protons in their nucleus called the atomic number.Ī chemical element is considered to be the simplest form of a substance , that is, a substance that no chemical reaction can further decompose. That is why the chemical element only contains one class of atoms . The symbols of some of the best known chemical elements are:Ĭhemical symbols are also used to abbreviate the elements that make up a certain matter such as, for example, water is made up of two molecules of hydrogen and 1 of oxygen, which is why it carries the chemical symbol of H2O Chemical Element and Chemical Symbol: Chemical symbols help everyone regardless of the language they use to identify the element according to the chemical universal symbol given to each of the elements.
