iron
Let an agent explain iron as an element, material and nutrient, describe its production, uses and corrosion, provide nutrition and medication information with attribution, and describe its isotopes.
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 iron as an element, material and nutrient, describe its production, uses and corrosion, provide nutrition and medication information with attribution, and describe its isotopes.
A metallic chemical element, atomic number 26, the most used metal in the world as the basis of steel, abundant in the Earth crust and core, with isotopes including the stable iron-56 and iron-57 and radioactive iron-52, iron-55, iron-59 and iron-60, and an essential nutrient carried in haemoglobin, given as a medication for iron deficiency; iron corrodes as rust and is recycled at scale.
What it is for: A structural metal and essential nutrient.
It can be explain properties and isotopes; describe production, steel and corrosion; provide nutrition and supplement information; describe iron in geology and astronomy.
