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.

History of Lise Meitner Olivia Mura, Haley Donovan, Robert Gahn
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
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
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
Meitners atom When neutrons and the atom collide the atom splits, releasing additional neutrons from the nucleus.
Meitners 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
Destruction Sadly, Lises discovery was not used for good. In 1945 the Uranium bomb was dropped on Hiroshima, which ended the war.
Model of the atoms Meitners atom Chadwicks atom
Similarities In both models, the neutron is the main particle Both models include all of the main 3 parts of an atom
Differences Chadwick discovered another part to an atom, where Meitner discovered a reaction when the particles are pushed a certain way. chadwicks discovery was used for good and Meitners was used for destruction
