ionisoitumisesta
Ionisoituminen, or ionization, is the physical process by which an atom or molecule acquires a negative or positive charge by gaining or losing electrons. This process results in the formation of an ion, which is an atom or molecule with a net electrical charge. Ionization can occur through various mechanisms, including collisions with other particles, absorption of radiation, or through chemical reactions.
One common method of ionization is through collisions. When a high-energy particle, such as a fast-moving electron
Another mechanism is photoionization, which occurs when an atom absorbs a photon of sufficient energy, typically
Ionization is a fundamental process in many areas of science, including plasma physics, chemistry, and astrophysics.
