Ionisation frees electrons

Ionization (or ionisation) 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 can result from the loss of an electron … Meer weergeven Everyday examples of gas ionization are such as within a fluorescent lamp or other electrical discharge lamps.
