Development of Bohr model due to atomic emission spectra of some
... Due to Newton’s law of energy conservation it is of course not possible that atoms can emit energy without energy being absorbed by them. So atoms only emit energy which they have obtained from an external source. According to Bohr, external energy is absorbed by the electrons around the nucleus. At ...

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.
