Chaotic ionization of a highly excited hydrogen atom
... Besides many systems, Rydberg atoms and wave packets have been particularly useful in studying how classically chaotic dynamics is manifested in their quantum-mechanical counterparts. This is because Rydberg atoms provide a real non-separable physical system with just a few degrees of freedom whose ...

Bonding Notes
... -Boy and Girl represent two free atoms that are not connected or bonded. Reading from left to right you can see that the two elements are not bonded and have a higher energy state than when bonded (Boy-Girl). Thus, the free atoms are not as stable as the bonded atoms. One can also observe that the m ...

Ionization
Ionization is the process by which an atom or a molecule acquires a negative or positive charge by gaining or losing electrons to form ions, often in conjunction with other chemical changes. Ionization can result from the loss of an electron after collisions with sub atomic particles, collisions with other atoms, molecules and ions, or through the interaction with light. Heterolytic bond cleavage and heterolytic substitution reactions can result in the formation of ion pairs. Ionization can occur through radioactive decay by the internal conversion process, in which an excited nucleus transfers its energy to one of the inner-shell electrons causing it to be ejected.
