bismuth
Let an agent explain bismuth and its properties and isotopes, describe its uses and production, relay safety information, and support chemistry learning.
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 bismuth and its properties and isotopes, describe its uses and production, relay safety information, and support chemistry learning.
A chemical element with atomic number 83, a brittle silvery-pink heavy metal that is the most diamagnetic element, has low toxicity compared with its neighbours lead and polonium, forms colourful oxide-layer crystals, and occurs as many isotopes of which bismuth-209 is effectively stable with an extremely long half-life; bismuth is used in pharmaceuticals, cosmetics, low-melting alloys, lead-free solders and shot, and is produced mainly as a by-product of lead and copper refining.
What it is for: A heavy metal element.
It can be explain properties and isotopes; describe uses and production; relay safety information; support learning.
Distinguishing features
Most diamagnetic element
Low toxicity for a heavy metal

Low-melting alloys
What it looks like
Silvery-pink brittle metal, often as iridescent stepped crystals.
How it is recognised
Element 83
Iridescent oxide crystals
Lead and antimony are neighbouring elements with different properties
