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 rhodium as an element and its properties, describe uses in catalysis and industry, present supply and market information with attribution, and support learning.

The chemical element with atomic number forty-five, a rare, hard, silvery-white platinum group metal that is highly reflective and corrosion-resistant, with one stable isotope, rhodium-103, and many radioactive isotopes, obtained as a by-product of platinum and nickel mining mainly in South Africa and Russia, and used above all in catalytic converters to reduce nitrogen oxides, as well as in chemical catalysts, electrical contacts, jewellery plating and mirrors; rhodium is among the most expensive metals and its price is highly volatile.

What it is for: Element forty-five, a platinum group metal.

It can be explain the element; describe uses; present supply and market information; support learning.
