Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the atomic number?107
2. What is the element symbol?Bh
3. How do scientists make Bohrium?Scientists create Bohrium by smashing heavy atoms, like bismuth or lead, with lighter atoms such as chromium or iron inside powerful particle accelerators.
4. Why does Bohrium disappear so quickly?All known Bohrium atoms are highly radioactive and have very short half‑lives. The most studied isotope, 270Bh, lasts about 2.4 minutes before it breaks apart.

Transactinide Element: Elements with atomic numbers greater than 103, existing beyond the actinide series.
Relativistic Effects: Quantum mechanical effects that become significant for heavy elements due to their high atomic numbers and electron speeds.
Island of Stability: A theoretical region of the chart of nuclides where superheavy elements are predicted to have significantly longer half-lives.
