curium
Let an agent explain curium and its discovery, relay properties, isotopes and applications from chemistry references at a public level, describe its role in space instruments, and distinguish curium from neighbouring actinides such as americium and berkelium.
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 curium and its discovery, relay properties, isotopes and applications from chemistry references at a public level, describe its role in space instruments, and distinguish curium from neighbouring actinides such as americium and berkelium.
A synthetic radioactive actinide element with atomic number 96, symbol Cm, first made in 1944 by Seaborg, James and Ghiorso and named after Marie and Pierre Curie, produced in nuclear reactors by neutron capture in plutonium, with isotopes from curium-232 to curium-252 of which curium-244 and curium-247 are the most used; curium is a strong alpha emitter used in radioisotope power sources and alpha particle X-ray spectrometers on space probes. The model gives public reference information only.
What it is for: Not applicable; a chemical element.
It can be explain the element; relay properties and isotopes; describe applications; distinguish related elements.
