Niels Bohr was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory. He received the Nobel Prize in Physics in 1922 for his work adapting Rutherford's nuclear atom model. Bohr introduced the idea that electrons occupy discrete energy levels and can jump between these levels by emitting or absorbing photons. Throughout his career, Bohr advocated for the peaceful use of nuclear energy and worked on the Manhattan Project during World War II before returning to Copenhagen.

1. Niels Bohr
Born:7 October 1885
Died:18 November 1962
Nationality:Danish
Fields:Physics

2. Biography
1912 He married his wife,
Margrethe Norlund.
He fathered six children, two of
them died.
One of their sons, Aage Bohr,
grew up to be an important
physicist who in 1975 also
received the Nobel Prize

3. Physics
In 1912 he met and later joined Ernest
Rutherford at Manchester University.
In 1922, Bohr was awarded the Nobel
Prize in physics.
Bohr had adapted Rutherford's nuclear
structure .

4. Bohr model of the atom(part I)
1.The electrons can only travel in certain
orbits.
2.The electrons of an atom revolve around
the nucleus in orbits.

5. Bohr model of the atom (part II)
Bohr introduced the idea
that an electron could drop
from a higher-energy orbit
to a lower one, in the
process emitting a
photon(light quantum) of
discrete energy.

6. Later, He succeeded in
founding the Institute of
Theoretical Physics in 1921,
of which he became director
In 1926 Bohr and
Heisenberg mapped and
explored the quantum
universe inside the atom
and finally Bohr won the
Franklin Medal award.
Bohr–Einstein debates

7. Before Mundial War II
In September 1941, Bohr was visited
by Heisenberg in Copenhagen

8. Second Mundial War
In September 1943, reliable word reached Bohr
about his imminent arrest by the German police.
Bohr and his wife escape by sea to Sweden.

9. Atom Bomb
Bohr Worked in the
Manhattan project

10. Later years
Bohr returned to Copenhagen,
He continued to advocte the peaceful use of nuclear
enegy.
