... In the early 1920’s it was becoming apparent that there were some difficulties with the Bohr model of the atom. One difficulty was that Bohr used classical physics to calculate the orbits of the hydrogen atom but this could not be used to explain the ability of electrons to stay in only certain ener ...

How are quantum numbers used to describe electrons
... What rules are used to explain how electrons fill orbitals? Pauli exclusion principle—no two electrons in an atom can have the same set of four quantum numbers If electrons are in the same orbital, they must have __________________spins so the fourth quantum number is different. We illustrate this b ...

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.
