Degree of Ionization

The degree of ionization (also known as ionization yield in the literature) refers to the proportion of neutral particles, such as those in a gas or aqueous solution, that are ionized into charged particles. A low degree of ionization is sometimes called partially ionized, and a very high degree of ionization as fully ionized.

Ionization refers to the process whereby an atom or molecule loses an electron, resulting in two oppositely charged particles, (1) a negatively charged electron and (2) a positively charged ion.

    “Words are made for a certain exactness of thought, as tears are for a certain degree of pain. What is least distinct cannot be named; what is clearest is unutterable.”
    —René Daumal (1908–1944)

    “There is always a degree of ridicule that attends a disappointment, though often very unjustly, if the expectation was reasonably grounded; however, it is certainly most prudent not to communicate, prematurely, one’s hopes or one’s fears.”
