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. He received the Nobel Prize in Chemistry in 1908. Ernest Rutherford (18711937) postulated the nuclear structure of the atom, discovered alpha and beta rays, and proposed the laws of radioactive decay. 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. Through his inventive experimental work Rutherford made many new discoveries in both radioactivity and nuclear physics. Millikan’s contribution to atomic theory was finding the charge of a single electron to be negative 1.602 x 10-19 C. This captivating journey takes us through the intricate web of Millikans experiments that ultimately unveiled the true nature of atoms. She also measured how radium, polonium, and uranium affected the air, which allowed her to see just how radioactive each was. One such breakthrough was Robert Millikans Atomic Theory, which revolutionized our perception of matter and laid the foundation for modern atomic physics. He did so with is now famous oil drop experiment where he was.
When Democritus proposed the atomic theory of matter, he suggested that: A) atoms were tiny, spherical particles of matter too small to be seen. Robert Millikan won his Nobel Prize for measuring the elementary charge of an electron. What contributions to the Atomic theory were made by, J.
These discoveries came from her numerous experiments involving radium, which she would usually get from pitchblende that she crushed. Millikan oil-drop experiment, first direct and compelling measurement of the electric charge of a single electron. Become a member to unlock this answer Create your account. She had also discovered both Polonium and Radium, naming them after Poland and the word Ray respectively. 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. Democritus developed the theory of the basic atom.
Marie had eventually gone to Paris and married Pierre Curie, and after feeling homesick, had returned to Poland. Democritus came up with the most basic atom and the basic rules of the atom. 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. 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. Marie Curie was born in Warsaw, Poland, and lived from 1867-1934.
