einsteinium
Let an agent explain einsteinium and its discovery, relay properties, isotopes and research uses from chemistry references at a public level, describe the isotopes the registry aliases name as a group, and distinguish einsteinium from neighbouring actinides such as californium and fermium, without operational nuclear detail.

What it is Filled
A synthetic radioactive actinide element with atomic number 99, symbol Es, discovered in 1952 in the debris of the first hydrogen bomb test and named after Albert Einstein, produced in minute quantities in high-flux reactors, with isotopes from about einsteinium-240 to einsteinium-258 of which einsteinium-252 has the longest half-life of about 472 days and einsteinium-253 is the most available; einsteinium is used only in research. The model gives public reference information only.
Why it exists Filled
Let an agent explain einsteinium and its discovery, relay properties, isotopes and research uses from chemistry references at a public level, describe the isotopes the registry aliases name as a group, and distinguish einsteinium from neighbouring actinides such as californium and fermium, without operational nuclear detail.
Distinguishing features Filled
- Synthetic actinide
- Micrograms only
- Named for Einstein
- Research use
What robots and AI may and may not do Filled
Must not
- Provide production, handling or weapons-related nuclear detail.
- Assist in acquiring or moving radioactive material outside lawful channels.
- Downplay its radiotoxicity.

Only with a human decision
- Any action involving real radioactive material.
May
- Explain einsteinium's history and properties in general terms, citing chemistry sources.
Moral aspects Filled
- Radioactive materials can harm people and are controlled for good reason.
