copernicium
Let an agent explain copernicium, relay its place in the periodic table, its synthesis and its properties from science sources, describe the isotopes its aliases name, and distinguish it from lighter, stable elements.
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 copernicium, relay its place in the periodic table, its synthesis and its properties from science sources, describe the isotopes its aliases name, and distinguish it from lighter, stable elements.
A synthetic, highly radioactive chemical element with atomic number 112, one of the superheavy elements made only in tiny amounts in particle accelerators and existing only briefly before decaying; the registry aliases name specific isotopes. Named after the astronomer Copernicus, it sits among the post-transition metals in the periodic table, though its chemistry is barely studied because so few atoms have ever been made. This is a chemistry and physics topic described at a general level.
What it is for: Not applicable; a synthetic chemical element.
It can be explain the element; relay its synthesis and decay; describe its isotopes; distinguish it from stable elements.
Distinguishing features
Atomic number 112
Synthetic
Highly radioactive
Made in tiny amounts
What it looks like
Never seen in bulk; only a few atoms have existed, so its bulk appearance is unknown.
Physical character
atomic number: 112 note
nature: synthetic, radioactive, short-lived note
registry parent: post-transition metal note
How it is recognised
Synthetic superheavy element, atomic number 112
Isotopes such as copernicium-285
Lighter elements are stable and abundant; copernicium exists only fleetingly
