Ionisation (Noun)
Meaning 1
The process of ionizing; the formation of ions by separating atoms or molecules or radicals or by adding or subtracting electrons from atoms by strong electric fields in a gas.
Classification
Nouns denoting natural processes.
Examples
- Ionisation occurs when an electron is removed from a neutral atom or molecule, resulting in the formation of a positively charged ion.
- The process of ionisation is often used in mass spectrometry to analyze the composition of a sample.
- Ionisation can occur through various mechanisms, including photoionisation, where high-energy photons are used to remove electrons from atoms or molecules.
- In a plasma, ionisation is the process by which neutral atoms or molecules are converted into ions and free electrons.
- The ionisation energy of an atom or molecule is the minimum amount of energy required to remove an electron from the outermost energy level.
