Similarities Between Thomson And John Dalton
Chemistry Midterm Essay
Describe a major contribution to science made by each of the following scientists:
John Dalton, (b) J. J. Thomson, (c) Robert Millikan, (d) Ernest Rutherford.
John Dalton was a chemist and a meteorologist, with his notable achievements being leading the study on color blindness and modern atomic theory. Born in 1766, his later research on color blindness stemmed from his experience with the condition along with his brother. Along with this, what is now known as Dalton’s Law of Partial Pressures comes from Dalton and his experiments with testing the pressure on mixed gases.
J.J. Thomson, a physicist, is responsible for pioneering the discovery of electrons with his research on cathode rays. He argued that the cathode rays consist of particles …show more content…
Ten years after graduating from Oberlin College in Ohio, he set out to determine what a single electron’s electric charge was through a multitude of experiments. He performed the Atomic Theory and Oil Drop experiment.
Ernest Rutherford is known as the father of nuclear physics. He first researched the magnetic properties of iron, and radioactive bodies. Rutherford discovered radon, a new noble gas. He influenced many other people who went on to win Nobel Prizes.
Discuss the arrangement of the periodic table. Who created the periodic table we still use today? How is the periodic table arranged (what patterns exist)? What characteristics do the rows and families (aka groups) share and how do they differ?
The periodic table was created by Dmitri Mendeleev in 1869, and arranged it still similarly to how it is now, which is by atomic mass and other similarities between elements.
The periodic table functions best in the way it is arranged, benefitting chemists because of its structure and usage. The layout of the table is arranged with electrons in layers surrounding protons and
