... Light is not alone in having properties of both waves and particles. In 1924, Louis de Broglie proposed that other small particles of matter can also behave as waves. Thus, his equation is not limited to electromagnetic radiation. In 1927, this was demonstrated by two separate experiments. Americans ...

... The problem with classical physics of the time was that an electron orbiting a nucleus would lose energy & eventually collapse into the nucleus. In Bohr’s model, an electron can travel around a nucleus without radiating energy. Furthermore, an electron in a given orbit has a certain definite amount ...

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.
