عن Bohrium
Bohrium was first synthesized at the GSI Helmholtz Centre by bombarding bismuth with chromium ions. Limited studies suggest rhenium-like behavior.
Uses & Applications
No practical applications. Scientific research only.
حقيقة مضحكة
Bohrium was created by fusing bismuth and chromium nuclei, producing just a few atoms at a time.
