Ionization - Wikipedia
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.
Ionization | Definition, Examples, & Facts | Britannica
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 energy to matter.

2023年6月18日 · Ionization is a process that changes the electrical charge of atoms or molecules by gaining or losing electrons. Ionization can occur in various ways, such as through collisions, chemical reactions, or exposure to electromagnetic radiation.
Ionization - Energy Education
Ionization 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 ).
What is Ionization? (with pictures) - AllTheScience
2024年5月21日 · Ionization is when an atom or molecule gains either a positive or negative charge. It can occur in one of two ways: first, when electrons are either gained or lost by a particle; second, when one atom or molecule combines with another atom or molecule that already has a charge.
What Is an Ion? Chemistry Definition - Science Notes and Projects
2021年11月20日 · In chemical reactions, ions form when atoms or molecules gain or lose valence electrons. Only nuclear reactions change the number of protons in a chemical species. The two types of ions are anions and cations. An anion has a net negative electrical charge. It contains more electrons than protons.
Definition of ionization - Chemistry Dictionary
Strictly defined, ionization is the complete loss of an electron from an atomic or molecular species. The resulting species is called an ion. In chemical equations, the charge on ions is shown as a superscript, such as in this simple ionization reaction: Ions may ionize further: Positively charged ions are often referred to as cations.
Ionization - Explanation, Formation and FAQs - Vedantu
Ionization can be defined as when a neutral atom or molecule can be converted into electrically charged atoms by gaining or losing a free electron. Ionization happens during the process of a chemical reaction. To ionize an atom or a molecule, either loses or gains electrons―the electron which is either gained or lost forms an ion.
Ion | Definition, Chemistry, Examples, & Facts | Britannica
2024年11月6日 · Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions. Ions migrate under the influence of an electrical field and are the conductors of electric current in electrolytic cells.

Electrons can move from one atom to another; when they do, species with overall electric charges are formed. Such species are called ions. Species with overall positive charges are termed cations, while species with overall negative charges are called anions.
