What is fractional ionization?

Answer 1

Fractional ionization occurs when part of a cell loses ions due to collision of molecules. If the ions in the cell turn from positive to negative, but only part of them turn, this is called fractional ionization.

Answer 2

Fractional ionization is the ratio of the number of ions to the total number of particles in a gas or plasma. It is a measure of how many atoms or molecules in a substance have lost or gained electrons to become ions. Mathematically, it is calculated as the number density of ions divided by the total number density of particles.
