atom
Let an agent explain atomic structure and models, describe how atoms determine chemistry, explain exotic atoms and atomic-scale measurement, and support learning across levels.
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 atomic structure and models, describe how atoms determine chemistry, explain exotic atoms and atomic-scale measurement, and support learning across levels.
The basic unit of a chemical element, consisting of a nucleus of protons and neutrons surrounded by electrons, with the number of protons defining the element and the electron configuration determining chemical behaviour, and including exotic atoms such as muonic atoms and protonium in which other particles replace electrons or protons; atoms combine into molecules and are described by quantum mechanics.
What it is for: The units of chemical elements.
It can be explain atomic structure; relate atoms to chemistry; describe exotic atoms; support learning.
