Atomic Model Timeline By: Mary Wurzbach Aristotle Aristotle was born in 384 B.C. and died in 322 B.C. He was born in Stageria, Greece Aristotle developed a theory that was based on the four elements which were discovered by him. He thought there was a quality to each of the elements. Democritus He was born in 460 B.C. and died in 370 B.C. Democritus was born in Abdera, Thrace in Greece He created the first atomic model Leucippus Leucippus was born in the 5th century B.C. and died in 5th century B.C. He was born in Miletus, Greece He founded the Atomistic Theory Ancient Greek and Roman Philosphers Democritus
Leucippus Atomic Model Scientists From 500-1700 Sir Isaac Newton John Dalton John Dalton was born on September 6th, 1766 and died on July 27, 1844. Nicolaus Copernius Born on February 19, 1473 and died May 21, 1543 Sir Isaac Newton He was born on January 4th 1643 and died on March 31, 1727 Atomic Model Scientists from 1701-1800 John Dalton Born on October 7, 1885 He was born in Eaglesville, Cumberland, England He contributed to the atomic model by proposing an atomic model proved by experiments. He is from Woolsthorpe, Lincolnshire, England He founded calculus and physics as well as optics. nicolaus coperinus Born in Torun, Poland Copernicus made a "Copernican Revolution," which is that the planets are rotating around the sun and the slower planets were farther away from the sun. Roger Bacon He was born in 1220 A.D and died in 1292 He was born in Ilchester, Somerset, England Atomic Model Scientists from 1801- 1885 Antonine-Laurent de Lavoisier He was born on August 26, 1743 and died on May 8, 1794 Roger Bacon believed science should be based on experimental evidence. Lavoisier He was born in Paris, France Lavoisier created the Law Conservation of Mass. He stated that mass isn't destroyed when a chemical reaction occurs. Joseph Priestly Born on March 13, 1733 and died on February 6, 1804 Born in Bristall Fieldhead, West Yorkshire, England Priestly was a chemist and preacher who discovered carbon dioxide as well as oxygen. Joseph Priestly Roger Bacon Neils Bohr Born in Copenhagen, Denmark Bohr is known as the father of the Quantum Theory and applied it to atomic and molecular structure. Marie Curie She was born on November 7, 1867 in Warsaw, Poland. Curie won the Nobel Peace Prize for Physics and Chemistry. She won these awards because she isolated new elements by their radioactivity. Wilhelm Roentgen He was born on March 27, 1845 and died on February 10, 1923 He was born in Lennep, Germany Roentgen discovered X-Rays while studying the path of a beam of electrons. James Chadwick He was born October 20, 1891 Chadwick was born in Manchester, England Werner Heisenberg Heisenberg was born on December 5, 1901 He discovered neutrons which led him to get the Nobel Peace Prize in 1935 for Physics. He was born in Wuerzburg, Germany. He won the Nobel Peace Prize in 1932 for Physics. By explaining that electron orbits can only be measured by the radiation they emit. Robert Millikan He was born on March 22, 1868 in Morrison, Illinois. He discovered the charge of an electron with his oil drop experiment. Henri Becquerel He was born on December 18, 1852 and died on August 25, 1903. Henri Becquerel discovered radioactivity, which is when an atom loses particles or energy. Ernest Rutherford He was born August 30, 1871 He was born in Brightwater, New Zealand JJ Thompson He was born on December 18, 1856 and died on August 30, 1940.
He was born in Cheetham, England. He was known as the "Father of Nuclear Physics" because he discovered alpha rays and beta rays. JJ discovered the proton. He is from Paris, France JJ Thompson Wilhelm Roentgen Henri Becquerel Atomic Model Scientists from 1886-1900 Bohr Marie Curie Robert Millikan Atomic Model Scientists from 1901-1920 Ernest Rutherford James Chadwick Werner Heisenberg The Plum Pudding Model websites The Plum Pudding Model was discovered by JJ Thompson in 1897. JJ Thompson explained that each atom had positively charged fluid floating around the atom sphere. http://www-outreach.phy.cam.ac.uk/camphy/nucleus/nucleus1_1.htm http://library.thinkquest.org/28582/history/plum.htm Electron Cloud Marie Curie died on July 4, 1934. Millikan died on December 19, 1953 Neils Bohr died on November 18, 1962. Rutherford died on OCtober 19, 1937. He passed away on July 24, 1974. He died on February 1, 1976. Atomic Model Scientists From 1921- 1975 Erwin Schroedinger Otto Hahn Otto was born on March 8, 1879 in Frankfurt am Main, Germany. Erwin Schroedinger He was born in Vienna, Austria on August 18, 1887. Albert Einstein Einstein was born on March 14, 1879 in Ulm, Wurttemburg, Germany. Albert Einstein Otto Hahn He was best known for having made contributions to radioactivity by discovering new radioactive elements. He died on July 28, 1968. Along with all of his other discoveries, Einstein had a hypothesis for the particle nature of light and also for his general theories of realitivity. He died on April 18, 1955. The movement of an electron in an atom as a wave was explained by Schroedinger. He died on January 4, 1961. An electron cloud is described as an atomic nucleus surrounded by a negative charge region associated with the atomic orbital. Rutherford - Bohr Model The Rutherford Bohr Model shows the electrons orbiting the nucleus and have a set size and energy. The Planetary Model also known as the Rutherford Model, is the earliest Greek Model. Planetary Model The Fruitcake atom is a solid positive sphere with negative electrons in like rasins in a cookie. The Fruitcake Atom This experiment was conducted by Rutherford. He found out most of the atoms went through the gold foil, but some were deflected. Gold Foil Experiment In 218 B.C- Hannibal invaded Italy. World Events in the Ancient Greek and Roman Times In the year 0, Jesus Christ was born Caligula is killed and Claudius was proclaimed Emperor in 41 A.D. Muhammad was born in 570. World Events for A.D. 500- 1700 1337- the Hundred's Years War Begins 1482 - Leonardo Da Vinci paints "The Last Supper" The Europeans started planting coffee in Brazil in 1727. In 1789, George Washington is the First President of the United States. World Events From 1701-1800 In 1716, the French build a fortress, one of the strongest in North America, at Louisbourg in Canada. 1801 is when Napoleon defeated Austria and took over the Holy Roman Empire. Timeline of the World from 1801-1885 Ohio becomes a state in 1803. In 1804, Lewis and Clark Began their Exploration. Timeline of World Events From 1886-1900 In 1925, there was the speech, "The Birth of the Nation." World Timeline of Events From 1901- 1920 In 1901, Teddy Roosevelt entered office. In 1919, Babe Ruth hits 2 home runs in one game. Adolf Hitler was appointed Chancellor in 1933. Timeline of World Events From 1921-1975 In 1931, the Star-Spangled Banner becomes the National Anthem. Amelia Earhart is the first lady to fly the Atlantic by herself.
