Definition of ionization energy

Ionization energy is the minimum amount of energy that an electron must absorb to escape nuclear influence. The concept is associated with the level of difficulty for an ion or atom to give up an electron. It is possible to express the ionization energy in kilojoules per mole (kJ/mol) or in electronvolts. Starting […]

Definition of electron affinity

Electronic affinity is the expression used by Chemistry experts to account for the energy that is released every time an atom that is neutral and in a gaseous state accepts at least one electron and, thanks to this, is formed into an ion of character. mononegative. This process, also known as electroaffinity, […]

Definition of energy levels

Energy levels come into play and become visible in multiple contexts. In the field of health, for example, this idea is related to the strength or vitality that can be gained or lost depending on someone's age, lifestyle or habits. Not having a balanced diet […]

Definition of Van der Waals forces

Van der Waals forces are interactions between molecules, as studied in the field of physical chemistry. This class of intermolecular forces are characterized by presenting anisotropy (a condition that indicates that their properties depend on the orientation of the molecules) and were named after a prominent physicist and professor of […]

Definition of equilibrium constant

The equilibrium constant is the expression of the relationship between the concentrations of the reactants and products in a chemical reaction when these levels do not change over time. In these cases, the chemical reaction reaches a state of equilibrium under certain conditions of temperature and pressure, with which it no longer […]

Definition of electrolysis

Electrolysis is the name of a process through which, by applying electricity, the elements of different chemical compounds are separated. Through the use of electric current, chemical experts maintain, substances in solution can be broken down into ions. The multifaceted Englishman William Nicholson, as the story goes, was […]

Definition of chemical kinetics

Chemical kinetics is the name of a specialty within the field of physical chemistry that focuses on the study of reaction speed. Its purpose is to establish, experimentally, how fast a certain chemical reaction happens and how the effect of temperature and issues linked to […]

Definition of astrochemistry

Astrochemistry is the name of an interdisciplinary science that focuses its attention on the study of the physical processes of the stars and the composition of the material that is found in interstellar space and that, generally, is concentrated in molecular clouds of considerable dimensions. In this discipline, useful to […]

Definition of spectroscopy

Spectroscopy is the name that identifies, within the field of Physics, the discipline that is responsible for studying the various types of spectra. Those who specialize in it focus their attention on the interaction that involves both matter and electromagnetic radiation, taking into account their generation or […]

Definition of metalloid

Metalloid is a concept from the field of Chemistry that is used to identify those chemical elements whose particularities linked to ionization and bonds are halfway between the distinctive properties of both metals and non-metals. Semimetals, a name that is accepted as a synonym […]
