It did eventually catch up to her however, and she died of aplastic anemia. Also, she survived a very long time for someone who messed around with radioactive materials. Some interesting facts about Marie Curie are that her name isn't actually Marie, but is instead Maria by birth! SHe changed it after marrying Pierre, and it is how she is most known. She also measured how radium, polonium, and uranium affected the air, which allowed her to see just how radioactive each was. These discoveries came from her numerous experiments involving radium, which she would usually get from pitchblende that she crushed.

She had also discovered both Polonium and Radium, naming them after Poland and the word Ray respectively. The life of Niels Bohr was an exciting one for science. Marie's biggest contribution to the atomic theory was that atoms' arrangement did not lead to them being radioactive, but that the atoms themselves were radioactive instead. Niels Henrik David Bohr (Danish: nels bo 7 October 1885 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Marie had eventually gone to Paris and married Pierre Curie, and after feeling homesick, had returned to Poland. This model showed how electrons moved towards, and away from the nucleus of an atom via the energy that the electrons had. He proposed that electrons are arranged in concentric circular orbits. Electrons have negative charge, protons have positive charge whereas neutrons have no charge, they are neutral. The theory that Niels Bohr came up with was the Bohr Model. In 1913, Neils Bohr, a student of Rutherford s, developed a new model of the atom. This atomic model is known as the quantum mechanical model of the atom. Schrödinger used mathematical equations to describe the likelihood of finding an electron in a certain position. The main postulates of the model are: An atom is made up of three particles : electons, protons and neutrons. What did Erwin Schrödinger contribute to the atomic theory In 1926 Erwin Schrödinger, an Austrian physicist, took the Bohr atom model one step further.

She worked as a tutor to gain the funds for both herself and her sister to receive education, and in her free time, Marie would read up on chemistry books. In 1912, Niels Bohr put forward a model to explain the structure of an atom. She had many obstacle in life to overcome, such as the fact that she was a girl, which meant she could not get higher education, and the fact that her dad could not put her into university because of money constraints. She had her mother die when Marie was only 10, and this led Marie to be put into boarding school. This concise 1924 volume provides an English translation of a 1923 German language essay which appeared in the Zeitschrift fr Physik journal.

Marie Curie was born in Warsaw, Poland, and lived from 1867-1934. Bohr won the 1922 Nobel Prize in Physics for his theory proposed in 1913 describing the atomic structure of the hydrogen atom based on quantum theory as a.
