Saha ionization equation

Meghnad Saha (mathematician and astro-physicist, developer of the Saha ionization equation)

The Saha ionization equation, also known as the Saha-Langmuir equation, is an expression that relates the ionization state of an element to the temperature and pressure.

In accordance with the Saha ionization equation, the most stable electron configurations are neon-like with 10 electrons remaining and nickel-like with 28 electrons remaining.

The results of the quantum Boltzmann gas are used in a number of cases including the Sackur-Tetrode equation for the entropy of an ideal gas and the Saha ionization equation for a weakly ionized plasma.
