Bohrium (version 1)

Bohrium (version 1) - Periodic Table of Videos

Introduction

This video from the "Periodic Table of Videos" series discusses Bohrium, an element named after the famous physicist Niels Bohr. The video provides an overview of Bohr's contributions to atomic structure and shares an interesting historical anecdote involving Bohr during World War II.

Main Points

• Niels Bohr's Contributions:

- Niels Bohr, a Danish physicist, was a pioneer in the field of atomic structure.

- He is renowned for his model of the atom, which introduced the concept of electron orbits.

• Bohr's Residence:

- Bohr was given a house by the Carlsberg brewery, which was equipped with a tap that dispensed lager directly from the brewery next door.

• World War II Anecdote:

- During World War II, German Nobel Prize winners Otto Hahn and Max Planck entrusted their gold Nobel Prize medals to Bohr for safekeeping.

- As Germany invaded Denmark, Bohr's colleagues dissolved the gold medals in aqua regia (a mixture of hydrochloric and nitric acid) to hide them.

- The solution was left on a shelf and went unnoticed by the Nazis.

- After the war, the gold was recovered from the solution, and the Nobel medals were reissued to their rightful owners.

Conclusion

The video highlights the fascinating life of Niels Bohr and his contributions to science, as well as a clever act of wartime subterfuge involving the dissolution and recovery of Nobel Prize medals. This story adds a personal and historical dimension to the understanding of Bohrium and its namesake.
