### action:

Ionization
* also produces light.
* begins first in the low-pressure chamber.
* can also occur through a collision with a particle
  - alter the functions of biological molecules fundamentally and often irreversibly
  - occur through tunneling of the excited electron into vacant levels in the metal
* changes the atom
  - plasma density
* cooling is the base line method for muon cooling.
* critical event in the now burgeoning analytical technique called mass spectrometry.
* cuts the size of the water molecular cluster in half.
* differs from the ion formation that occurs in ordinary chemical reactions.
* energies for neutral atoms are also available on a hyperlinked periodic table.
* happens by giving atoms high energy.
* increases the number of particles, while thermalization decreases it.
* is a. the removal of an electron from a neutral atom
  - by electron impact or fast atom bombardment
  - caused by a gain or loss of electrons
  - conditions
  - likely to occur when an atom has a partially occupied outer electron energy level
* is the key to plasma production and can be accomplished in many different ways
  - only reliable means of eliminating static on non-conductors
* is the process by which electrons are removed from an atom
  - neutral atoms are converted to charged species
* is the process of breaking larger groups of molecules in to smaller groups of molecules
  - generating a gas phase ion from an otherwise neutral chemical species
* kills bacteria and algae.
* major advance in the non-chemical purification of drinking water.
* means many free electrons in the core.
* occurs when electrons are dislodged from a neutral atom.
* particular characteristic of the radiation produced when radioactive elements decay.
* process in which an electron is stripped off of a particle.
* processes for mass spectrometry.
* simply means to gain or loose an electron.
* takes place inside the unit to avoid particles sticking to walls in a room.
* thresholds and strongest lines of atoms and ions.
* uses electronically produced copper and silver ions to purify a body of water.
+ Hollow-cathode lamp, Excitation Process: Lamps
  * The excitation process of the element of interest takes place through a few steps. First, the inert gas contained inside of the glass tube is ionized by a voltage. Ionization is the process by which neutral atoms are converted to charged species. This current allows for electrons to move to the anode and cathode. If the voltage applied is large enough, the ions of the inert gas gather enough energy to remove some of the metal atoms of interest from the surface of the cathode by striking the surface. The removal of these atoms produces a cloud around the cathode. The process of producing this cloud is called sputtering. Some of these metal atoms in the cloud have moved to an excited energy state and as they return to their ground state, they emit a specific radiation which is characteristic to the metal of interest.
+ Ion, Physics: Chemistry
  * Ionization happens by giving atoms high energy. This is done using electrical voltage or by high-energy radiation.
