Chapter 14: Phenomena Chapter 14 Covalent Bonding: Orbitals
... Phenomena: Scientists knew that in order to form a bond, orbitals on two atoms must overlap. However, px, py, and pz orbitals are located 90˚ from each other and compounds like CH4 (which would form bonds using their p orbitals) do not have bond angles of 90˚. Therefore, scientists had to explain th ...

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.
