ስለ Fermium
Fermium was co-discovered with einsteinium in hydrogen bomb debris. It is the heaviest element producible by neutron bombardment. Only tiny amounts have been made.
ፕሮግራሞች
No practical applications. Scientific research only.
ሐቅ
Fermium is the heaviest element producible by neutron bombardment. Anything heavier requires smashing nuclei together in accelerators.
