Medical Definition of Ionisation

1. Any process by which a neutral atom gains or loses electrons, thus acquiring a net charge, as the dissociation of a substance in solution into ions or ion production by the passage of radioactive particles. High temperatures, electrical discharges or nuclear radiations can cause ionisation. (16 Dec 1997)

Literary usage of Ionisation

Below you will find example usage of this term as found in modern and/or classical literature:

1. A Text-book of Physics by William Watson (1905)
"If the energy in the ionic state is the smaller, then ionisation will be accompanied by development of heat, which we may- call the "heat of ionisation. ..."

"[All the metals which are easily ionised show positive heats of ionisation ; the others show negative heats of ionisation.] * Especial stress should be laid ..."

3. Electro-chemistry by Robert Alfred Lehfeldt, T. S. Moore (1918)
