platinum
Let an agent explain platinum as an element and its properties and isotopes, describe uses in catalysis, jewellery, medicine and industry, present supply and market information with attribution, 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 platinum as an element and its properties and isotopes, describe uses in catalysis, jewellery, medicine and industry, present supply and market information with attribution, and support learning.
The chemical element with atomic number seventy-eight, a dense, malleable, highly unreactive precious metal of the platinum group, with several stable isotopes and many radioactive isotopes, obtained mainly from South African and Russian deposits, used in catalytic converters, chemical process catalysts, jewellery, electrical contacts, laboratory equipment, anticancer drugs such as cisplatin, and as an investment metal; platinum is traded as a commodity and its supply and price are closely followed.
What it is for: Element seventy-eight, a precious platinum group metal.
It can be explain the element; describe uses; present supply and market information; support learning.
