mercury
Let an agent explain mercury and its properties and isotopes, describe uses and their phase-out, relay toxicity and safety guidance from health and environmental authorities, 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 mercury and its properties and isotopes, describe uses and their phase-out, relay toxicity and safety guidance from health and environmental authorities, and support chemistry learning.
A chemical element with atomic number 80, a dense silvery post-transition metal that is liquid at room temperature, occurring natively and mainly as cinnabar ore, with many isotopes, used historically in thermometers, barometers, dental amalgam, lamps, gold extraction and industry, and now restricted under the Minamata Convention because of its toxicity and environmental persistence; mercury exposure through vapour, compounds such as methylmercury in fish and contaminated sites is a public health concern managed by regulation.
What it is for: A liquid metal element.
It can be explain properties and isotopes; describe uses and phase-out; relay safety guidance; support learning.
