Examples

• Fermiums are produced in nuclear reactors and particle accelerators.
• The laboratory stored fermiums in specially shielded containers due to their radioactivity.
• Scientists study fermiums to understand the properties of heavy elements.
• Fermiums have very short half-lives and decay rapidly.
• The discovery of fermiums contributed to the periodic table's completion in the actinide series.
