ionization
Let an agent explain ionisation and its mechanisms and energy requirements, describe its role in plasmas, radiation and analytical chemistry, support calculations with ionisation energies, and support learning.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain ionisation and its mechanisms and energy requirements, describe its role in plasmas, radiation and analytical chemistry, support calculations with ionisation energies, and support learning.
The process by which an atom or molecule acquires a positive or negative electric charge by losing or gaining electrons, occurring through collisions, heat, radiation, strong electric fields and chemical reactions, in forms such as photoionisation, thermal and air ionisation, molecular autoionisation and analytical techniques such as electrospray and desorption ionisation used in mass spectrometry; ionisation produces plasmas, underlies radiation effects on matter, and is fundamental in chemistry, physics and technology.
What it is for: Formation of ions by electron loss or gain.
It can be explain mechanisms; describe roles in science and technology; support calculations; support learning.
Distinguishing features
Charge formation
Ionisation energy

Plasma formation
What it looks like
Not visible directly; seen in plasmas, sparks and auroras.
How it is recognised
Atom or molecule gains or loses electrons
Collision, heat, radiation, field, chemistry
Excitation raises energy without ionising; dissociation splits molecules
