The process of converting atoms or molecules into ions by adding or removing charged particles. In Japanese, this is typically expressed with the noun イオン化 or the verb イオン化する.
The process of ionization in physics, chemistry, or general contexts.
The standard term for ionization in scientific and technical contexts. Can be used as a noun or with する to form a verb.
水のイオン化について学んだ。
I learned about the ionization of water.
この物質は加熱するとイオン化する。
This substance ionizes when heated.
A more traditional Japanese term for ionization, often used in physics and chemistry. Slightly more formal or academic than イオン化.
電離層は大気の上層部にある。
The ionosphere is in the upper atmosphere.
電離放射線の影響を調べる。
We investigate the effects of ionizing radiation.
Referring to the degree or state of being ionized.
Means 'degree of ionization' or 'ionization degree'. Used in technical descriptions.
溶液のイオン化度を測定する。
Measure the degree of ionization of the solution.
Means 'ionization state'. Used when discussing the specific ionic form of an atom or molecule.
鉄のイオン化状態によって色が変わる。
The color changes depending on the ionization state of iron.
The energy required to remove an electron from an atom or molecule.
The standard term for ionization energy in chemistry and physics.
ヘリウムのイオン化エネルギーは非常に高い。
The ionization energy of helium is very high.
An alternative term for ionization energy, using the traditional 電離. Less common but still used in some academic texts.
第一電離エネルギーを比較する。
Compare the first ionization energies.
イオン化 is the more common and modern term, widely understood. 電離 is more traditional and often appears in set phrases like 電離層 (ionosphere) or 電離放射線 (ionizing radiation). In general scientific writing, イオン化 is preferred.
