ion
Let an agent explain ions and their formation, naming and behaviour, support chemistry problem solving, and relate ions to biology, materials and technology.
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 ions and their formation, naming and behaviour, support chemistry problem solving, and relate ions to biology, materials and technology.
An atom or molecule with a net electric charge due to loss or gain of electrons, positively charged cations or negatively charged anions, including monatomic ions such as sodium and chloride and polyatomic ions such as sulfate, ammonium and bistriflimide; ions form ionic compounds, conduct electricity in solutions and plasmas, and are central to chemistry, biology and materials.
What it is for: Chemistry, biology and materials science.
It can be explain ion formation and charge; name and write formulas for ions; explain ions in solutions and biology; describe applications such as batteries and plasmas.
