Ionization Meaning ;
An ion is an atom or molecule that has lost or gained one or more electrons, giving it a net electric charge. The ionization energy is the energy required to remove an electron from an atom or molecule.
Ionization Energy and Formation of Ions
Ionization energy is the energy required to remove an electron from an atom in its gas phase. The higher the ionization energy, the harder it is to remove an electron from an atom. The energy required to remove an electron is also called the ionization potential.
The electrons in the outermost energy level of an atom are called the valence electrons. The valence electrons are the ones that are most likely to be removed from an atom.
The energy required to remove an electron from an atom is determined by the strength of the atom’s electron-attracting forces. The stronger the electron-attracting forces, the higher the ionization energy.
The electron-attracting forces are determined by the size of the atom’s nucleus and the number of protons in the nucleus. The larger the nucleus, the stronger the electron-attracting forces. The more protons in the nucleus, the stronger the electron-attracting forces.
Ions are atoms that have lost or gained electrons. When an atom loses an electron, it becomes a positively charged ion. When an atom gains an electron, it becomes a negatively charged ion.
Ions are formed when atoms interact with other atoms. When two atoms interact, the atoms may exchange electrons. When this happens, the atoms form ions.
Electron Ionization
The process of electron ionization is the process of removing an electron from an atom or molecule. This can be done by heating the atom or molecule to a high enough temperature, or by using a strong electric field. When the electron is removed, the atom or molecule becomes a positive ion.
Plasma Ionization
Plasma ionization is the process of ionizing a gas by bombarding it with energetic particles or photons. In the simplest case, a gas is ionized by a collision between a fast particle and a slow particle. The fast particle transfers its energy to the slow particle, which then recoils and ionizes adjacent atoms. This process can be repeated until the entire gas is ionized.
Ionization of Acids and Bases
Acids and bases can be ionized in water. This means that they can dissociate into ions in water.
An acid can dissociate into hydrogen ions (H+) and an anion.
A base can dissociate into hydroxide ions (OH-) and a cation.
The following equations show how an acid and a base can be ionized in water.
\begin{align*}\mathrm{HA}_{(aq)} & \mathrm{dissociates} \longleftrightarrow \mathrm{H}^{+}_{(aq)} \mathrm{+} \mathrm{A-}_{(aq)}\\ \mathrm{H}^{+}_{(aq)} & \mathrm{ionizes} \longleftrightarrow \mathrm{H}^{+}_{(g)} \mathrm{+} \mathrm{e}^{-}\\ \mathrm{A-}_{(aq)} & \mathrm{ionizes} \longleftrightarrow \mathrm{A}^{-}_{(g)} \mathrm{+} \mathrm{e}^{-}\end{align*}
The following table shows the ionization of some common acids and bases.

Ionization of Water
Water is a polar molecule and is ionized when it loses or gains one or more electrons. The water molecule has a positive end and a negative end. When an electron is lost, the water molecule becomes a positively charged ion, and when an electron is gained, the water molecule becomes a negatively charged ion.
