Ionization - Wikipedia
网页Ionization (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. The resulting electrically charged atom or molecule is called an ion.
Ionization | Definition, Examples, & Facts | Britannica
网页Ionization, 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. Ionization is one of the principal ways that radiation transfers its …
Ionize Definition & Meaning - Merriam-Webster
网页The meaning of IONIZE is to convert wholly or partly into ions.
Ionization energy | Definition & Facts | Britannica
网页2024年8月9日 · Ionization energy, in chemistry and physics, the amount of energy required to remove an electron from an isolated atom or molecule. The ionization energy associated with removal of the first (most loosely held) electron, however, is most commonly used.
Ionizing radiation | Definition, Sources, Types, Effects, & Facts
网页Ionizing radiation, flow of energy in the form of atomic and subatomic particles or electromagnetic waves that is capable of freeing electrons from an atom, causing the atom to become charged (or ionized).
Ionization - Energy Education
网页Ionization is the process by which ions are formed by gain or loss of an electron from an atom or molecule. [2] 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).
