Ionization - Wikipedia
WEBIonization (or ionisation specifically in Britain, Ireland, Australia and New Zealand) is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons, often in conjunction with other chemical changes.
Ionization | Definition, Examples, & Facts | Britannica
WEBionization, in chemistry and physics, any process by which electrically neutral atoms or molecules are converted to electrically charged atoms or molecules (ions) through gaining or losing electrons.
7.4: Ionization Energy - Chemistry LibreTexts
WEBTypical units for ionization energies are kilojoules/mole (kJ/mol) or electron volts (eV): 1 eV / atom = 96.49 kJ / mol. If an atom possesses more than one electron, the amount of energy needed to remove successive electrons increases steadily.
Ionization energy - Wikipedia
WEBIn physics and chemistry, ionization energy (IE) is the minimum energy required to remove the most loosely bound electron of an isolated gaseous atom, positive ion, or molecule. [1] The first ionization energy is quantitatively expressed as X(g) + energy X + (g) + e −
Ionization - Energy Education
WEBIonization is the process by which ions are formed by gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion ), and if it loses an electron, it becomes positively charged (a cation ).

WEBSep 16, 2020 · Ionization energy is denoted by the symbols IE, IP, ΔH° and has units of kilojoule per mole ( (kJ/mol) or electron volts (eV). Ionization energy is the energy required to remove an electron from an atom or ion. Ionization energy increases moving across a period and decreases moving down a group.
