Ionization potential — The ionization potential, ionization energy or EI of an atom or molecule is the energy required to remove an electron from the isolated atom or ion. More generally, the nth ionization energy is the energy required to strip it of the n th electron … Wikipedia
Critical ionization velocity — experiment onboard space shuttle Discovery (STS 39), releasing a plume of nitrous oxide gas. Full text Critical ionization velocity (CIV, also called Critical velocity, CV) is the relative v … Wikipedia
Tunnel ionization — is a process in which electrons in an atom (or a molecule) pass through the potential barrier and escape from the atom (or molecule). In an intense electric field, the potential barrier of an atom (molecule) is distorted drastically. Therefore,… … Wikipedia
Molecular orbital theory — In chemistry, molecular orbital (MO) theory is a method for determining molecular structure in which electrons are not assigned to individual bonds between atoms, but are treated as moving under the influence of the nuclei in the whole… … Wikipedia
Electrospray ionization — Electrospray (nanoSpray) ionization source Electrospray ionization (ESI) is a technique used in mass spectrometry to produce ions. It is especially useful in producing ions from macromolecules because it overcomes the propensity of these… … Wikipedia
HSAB theory — The HSAB concept is an acronym for hard and soft (Lewis) acids and bases. Also known as the Pearson acid base concept, HSAB is widely used in chemistry for explaining stability of compounds, reaction mechanisms and pathways. It assigns the terms… … Wikipedia
Saha ionization equation — The Saha ionization equation, also known as the Saha Langmuir equation, was developed by the Indian astrophysicist Megh Nad Saha in 1920, and later (1923) by Irving Langmuir. One of the important applications of the equation was in explaining the … Wikipedia
Hydridic Earth theory — The Hydridic Earth theory is a theory proposed in 1968 by Soviet geologist Vladimir Larin. The theory contradicts the generally accepted views on the Structure of the Earth. The theory makes certain predictions that can be falsified or proven… … Wikipedia
Self-ionization of water — The self ionization of water (also autoionization of water, and autodissociation of water) is the chemical reaction in which two water molecules react to produce a hydronium (H3O+) and a hydroxide ion (OH−):: 2 H2O (l) ightleftharpoons H3O+ (aq)… … Wikipedia
Atomic theory — Atomic model redirects here. For the unrelated term in mathematical logic, see Atomic model (mathematical logic). This article is about the historical models of the atom. For a history of the study of how atoms combine to form molecules, see… … Wikipedia
Bragg-Gray Cavity Theory — According to the Bragg Gray cavity theory, the ionization produced within a gas filled cavity inside a medium is related to the energy absorbed in that surrounding medium. If the cavity is small enough that it does not change the number or… … Wikipedia
