George De Hevesy Research Paper
George Charles de Hevesy was born on August 1, 1885, in Budapest, Austria-Hungary. George was the fifth of 8 children. He was born in to a wealthy family of industrialists (. He was the son of Louis de Hevesy and Eugénie, née Baroness Schosberger. George’s dad was a court counsellor. Growing up George didn’t have a relative associated with the scientific field, so his decision to become a chemist was made by him.

238 element uranium. George was given the task by Rutherford to separate the newly found radioactive isotope radium-d from ordinary lead. After about two years of trial and error, George came to the conclusion that the radium-d and lead were impossible to separate. According to McMurray, Emily J. editor of the Notable Twentieth-Century Scientists, the reasons his task didn’t work was because the lead he used, which is commonly referred to as lead-210 had the same number of protons and electrons, but had a different number of neutrons in its nucleus. Although Hevesy was not successful with the separation he learned more about radium-D and decided use radium-D to trace the course of lead in chemical processes. In 1913, George joined up with Friedrich Paneth at the Vienna Institute of Radium Research. George was able to conduct precise studies of lead salts by mixing an enormous amount of radium-D with regular lead salt. Then he determined the amount of salt dissolved by measuring the proportion of radioactivity in the solution. Both George and Friedrich proved that the electrochemical properties of radium-D were identical with lead. This added to the ever growing evidence of the existence of isotopes (Pg. 914). In 1922 with the help of Dirk Coster he co-discovered the element 72, hafnium. They were able to realize this

Richard Daley Research Paper
216 Words | 1 PagesRichard Joseph Daley (May 15, 1902 – December 20, 1976) was an American politician who was the Mayor of Chicago for 21 years (1955–1976) and chairman of the Cook County Democratic Central Committee for 23 years, holding both positions until his death in office in 1976. Daley was Chicago's third consecutive mayor from the working-class, heavily Irish American Bridgeport neighborhood on Chicago's South Side, where he lived his entire life. He is remembered for doing much to avoid the declines that some other "rust belt" cities like Cleveland, Buffalo and Detroit experienced during the same period.

His dad was named Abraham Rothstein and he was a businessman. However Abraham was usually dishonest and was it was unusual for him to tell the truth.
How Did Arthur Holmes Influence Modern Science
587 Words | 3 PagesThe technology Arthur Holmes used set him apart from other scientists, while still being accurate today. Arthur Holmes used uranium-lead radiometric dating to measure the age of rocks, which in turn, led to his accurate estimation of the Earth’s age, and the popularity of radiometric dating. Holmes’ prediction would have resembled predictions of other scientists of the time if he did not use the then remarkable, new technology of uranium-led radiometric dating. Although Holmes was the first to use uranium-lead radiometric dating, he did not invent it. Ernest Rutherford in 1905 created it, and Arthur Holmes was the first to accurately use it in 1911.
