silver
Let an agent explain silver as an element and material, support identification and purity questions, describe uses and markets with sourced data, and address health and environmental aspects.
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 silver as an element and material, support identification and purity questions, describe uses and markets with sourced data, and address health and environmental aspects.
A chemical element with symbol Ag and atomic number 47, a soft, white, lustrous precious and noble metal with the highest electrical and thermal conductivity of any metal, occurring as native silver and in ores, used in jewellery, coinage, electronics, photography, mirrors, medicine and as an investment metal; it has many isotopes, of which silver-107 and silver-109 are stable.
What it is for: Jewellery, industry, investment and medicine.
It can be explain properties and isotopes; identify silver items and purity; describe uses in industry and medicine; report prices and markets with sources.
