Lise Meitner was an Austrian/German physicist born in 1878 who made significant contributions to nuclear physics. She received her doctorate in 1905 as the second woman to earn a PhD from the University of Vienna. In 1938, Meitner, Otto Hahn, and Fritz Strassmann discovered nuclear fission when bombarding uranium with neutrons. This splitting of uranium atoms led to additional neutrons and the potential for an explosive chain reaction. Sadly, her discovery was later used in 1945 for the atomic bomb dropped on Hiroshima. Meitner received several honors for her work, including the Max Planck medal in 1949.

2. Bio of Ms. Meinter
● November 7th 1878- October 27
1968
● From 1901-1905 she went to the
University of Vienna and
became the second woman to
get a doctoral degree

3. Biography cont.
● She got the Lieben prize
in 1925, the Max Planck
medal in 1949, the Otto
Hahn Prize for Chemistry
and Physics in 1955, and
the Enrico Fermi Award
in 1966

4. Biography cont.
● In 1938 Lise, Otto Hahn, and Fritz
Strassmann were the first to
recognize that when an uranium
atom is bombarded by neutrons, it
splits, they called it Nuclear Fission
● She was born in Vienna, Austria and
died in Cambridge, United Kingdom

5. Meitner’s atom
When neutrons and the
atom collide the atom
splits, releasing additional
neutrons from the
nucleus.

6. Meitner’s atom cont.
● If enough atoms split at
once, it is likely to produce an
explosion.
● This is the method
that Lise Meitner used on Uranium which is
called Nuclear fission

7. Destruction
Sadly, Lise’s discovery
was not used for
good. In 1945 the
Uranium bomb was
dropped on
Hiroshima, which
ended the war.

8. Model of the atoms
Meitner’s atom Chadwick’s
atom

9. Similarities
● In both models, the neutron
is the main particle
● Both models include all of
the main 3 parts of an atom

10. Differences
● Chadwick discovered another part
to an atom, where Meitner
discovered a reaction when the
particles are pushed a certain way.
● chadwick’s discovery was used for
good and Meitner’s was used for
destruction
