magnesium
Let an agent explain magnesium as an element and its properties, relay isotopes, occurrence and production from chemistry references, describe alloys, biological roles and hazards, and distinguish magnesium from manganese and from magnesium compounds and supplements.
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 magnesium as an element and its properties, relay isotopes, occurrence and production from chemistry references, describe alloys, biological roles and hazards, and distinguish magnesium from manganese and from magnesium compounds and supplements.
A chemical element with symbol Mg and atomic number 12, a light, silvery alkaline earth metal that burns with a brilliant white flame, is the eighth most abundant element in the crust and the fourth most common in the body, essential to chlorophyll and hundreds of enzymes, used in lightweight alloys for vehicles and electronics, in reducing agents and flares, and known in isotopes from magnesium-19 through magnesium-40, of which magnesium-24, 25 and 26 are stable.
What it is for: Alloys, reducing agent, biological nutrient.
It can be explain properties; relay isotopes and occurrence; describe uses and biology; distinguish from manganese.
