metal
Let an agent explain metals and their properties and classes, describe uses, production and recycling, support selecting metals for applications, 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 metals and their properties and classes, describe uses, production and recycling, support selecting metals for applications, and support learning.
A material, usually a chemical element or alloy, that is typically hard, shiny, malleable, ductile and a good conductor of heat and electricity, with metallic bonding of delocalised electrons, including elements such as iron, copper, aluminium and gold, alloys such as steel, bronze and brass, and categories such as base, precious, ferrous, non-ferrous and heavy metals; metals underpin construction, transport, energy, electronics and tools, are produced by metallurgy and are extensively recycled.
What it is for: Conductive malleable materials.
It can be explain properties and classes; describe uses and production; support selection; support learning.
