... Theoretical explanation: modification of simple Bohr theory by Wilson and Sommerfeld: electron orbits can be elliptical, of which a circular orbit is a special case. Each orbit is specified by 2 parameters instead of 1. Geometrically by semi-major and semi-minor axes a,b, no just radius r. Thus, en ...

... Use a phrase to describe why the 2s orbital is more stable (lower energy) versus 2p. When you superimpose the total radial probability of 2s and 2p onto the plot of 1s, you notice that the 2s has a small peak that is inside the 1s shield, which causes them to have more exposure to the full nuclear c ...

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.
