| 单词 | ionization potential |
| 释义 | > as lemmasionization potential ionization potential n. Physics the energy required to remove an electron from an atom or molecule of a gas to an indefinite distance; the potential difference through which an electron must be accelerated to achieve this; spec. (more fully first ionization potential) the energy required to remove an electron in the lowest energy state (the least strongly bound electron).

G. Mortimer Physical Chem. (ed. 3) xix. 821/1 The ionization potential is found generally to decrease toward the bottom of a column of the periodic table. < as lemmas |
