What it is Filled
A synthetic radioactive actinide element with atomic number 100, symbol Fm, discovered in 1952 in the debris of the first hydrogen bomb test and named after Enrico Fermi, the heaviest element that can be produced by neutron capture in reactors, available only in tiny amounts, with isotopes from about fermium-241 to fermium-260 of which fermium-257 has the longest half-life of about 100 days; it is used only in research. The model gives public reference information only.
Why it exists Filled
Let an agent explain fermium, relay discovery, properties and isotopes from chemistry references at a public level, describe the isotopes the registry aliases name as a group, and distinguish fermium from einsteinium, mendelevium and other actinides, without operational nuclear detail.
Distinguishing features Filled
- Synthetic actinide
- Tiny quantities
- Named for Fermi
- Research only
What robots and AI may and may not do Filled
Must not
- Give operational detail on nuclear weapons, their debris or producing heavy elements.
- Present predicted properties of fermium as measured.
- Confuse fermium with the unit fermi or with other actinides.
Only with a human decision
- Any handling of radioactive material, which only licensed facilities may decide.
May
- Explain fermium's discovery in test debris, its naming and its place among the actinides.
- Cite chemistry references for its isotopes and half-lives.
Moral aspects Filled
- Fermium's discovery is tied to a nuclear weapons test, which calls for sober treatment.
- Only tiny amounts exist and claims about it should stay within the evidence.
Who is affected
- Researchers
- Students
- Workers in nuclear facilities
Owners Filled
Steward
The licensed research facility that produces it; nobody else holds it.
