Ernest Rutherford Research Paper

693 Words3 Pages

More than two thousand four hundred years ago, Democritus produced the theory that all matter contains tiny particles called atoms that are indestructible. Fast forward to year 1803 when scientist John Dalton stated new ideas that all atoms of a single element are identical in size and mass, atoms of specific elements have a different structure than those of other elements, and during a chemical change, atoms are able to separate and combine. Now go back 106 years from today and meet scientist Ernest Rutherford. Ernest Rutherford was conducting his gold foil experiment when he discovered what is known to be one of the greatest discoveries about the atomic theory. Rutherford produced a model of the atom with a dense nucleus in the center and electrons orbiting around it, he gave future scientists a better understanding of an atom, and he discovered two types of radiation. …show more content…

This was known as the “plum pudding” model. Ernest Rutherford put his hypothesis to the test in 1911 when he conducted the gold foil experiment. During this experiment, Rutherford blasted a sheet of gold foil with alpha particles and to his surprise, a few particles were rebounded and deflected back. This lead to his conclusion that there was a nucleus in the center of each atom which was causing the deflection of the particles. Rutherford once said, “We are rather like children, who must take a watch to pieces to see how it works”. His experiment and his quote connect like an analogy, where he took the previous idea of an atom and conducted an experiment in order to see how the atom really

While others thought it was a waste of time he found “As we know today, when a beam of electrons strike an atom, the beam punches out the atom’s own electrons, leaving a hole, Electrons are attached to an atom’s nucleus because electrons and protons have opposite charges, and tearing electrons away from the nucleus is a violent deed” (Kean123). Mosely began to fine tune and hunt for the missing elements, creating the atomic number, determining

On October 4th, 1822 in Delaware, Ohio the nineteenth president of our United States of America was born. After winning one of the most controversial presidential elections in history, Rutherford B. Hayes was secretly sworn into office, becoming the first president to take his oath in the White House. While only serving only one term in office (1877-1881) Hayes made incredible strides in Civil-Rights laws, results of which wouldn’t be seen until the next presidency, also dealing with the time after the Civil War, otherwise known as the Reconstruction period, and rebuilding a new America. The fifth child in the marriage of Rutherford Hayes Jr., who ran a whisky distillery, and Sophia Birchard Hayes, his fathers namesake Rutherford

What Was Rutherford's Accomplishments

Rutherford Birchard Hayes, the nineteenth president of the United States of America had many profound accomplishments before setting out on the campaign trail in 1876. Rutherford was born on October 4, 1822 in Delaware, Ohio, by his mother Sophia who had lost her husband, Rutherford’s father ten weeks earlier. Rutherford grew up in a house full of love and faith, which helped to smooth the rough times of growing up without a father, as well as losing two siblings. Rutherford earned the nickname “Rud” as he was growing up in Delaware, unable to play and socialize with other kids his age until he was seven years old due to his frail and unstable health in early years. With Rud couped up around the Hayes household for many of his early years,

How Did Millikan Determine The Number Of Oil Dropss

563 Words | 3 Pages

In the early 1900’s, Robert Millikan started studying the charge of an atom. He wanted to know whether there was a smallest unit of electric charge and if so, what is this charge and what is its magnitude in Coulombs. In order to test this he took small oil droplets and put them through an atomizer which ionized the oil droplets. He then placed the oil droplets in a closed system between two oppositely charged plates with the negatively charged plate on top. In order to figure out the value of ‘e’ (elementary charge) he had to find the electric force of the fields.

His vitreous fluid corresponds to what we now call positive charge, and the resinous fluid is now termed negative charge. Charge Carriers More than one hundred years after the work of Benjamin Franklin, the secrets of the atom itself began to be revealed. Moreover, in 1897, J.J. Thomson discovered the electron. Soon after, it was determined that these charged particles existed in all atoms and that a countercharge, carried by some other part of the atom, was necessary to make the overall charge of the atom neutral. In time, the proton was determined to carry this charge.

The Manhattan Project: James Chadwick And The Atomic Bomb

868 Words | 4 Pages

As flapper girls with chic haircuts kicked off their dancing shoes, the night and the roaring twenties coming to an end, a tall, slender Englishman by the name of James Chadwick sat hunched over in his lab, working to find a particle that no one, not even the world’s most brilliant minds of his time, was sure existed. His name was James Chadwick and for nearly a decade, he had been trying to prove the existence of neutral particles in the nucleus of the atom, neutrons. As the new decade began, Chadwick still had no tangible evidence proving his neutrons, and maybe he never would have if not for the work of Irene and Frederic Juliot-Curie. The two scientists had performed an experiment where they bombarded alpha particles at beryllium, producing

How Did Wilhelm Geiger-Muller Contribute To Chemistry

1096 Words | 5 Pages

A famous quote from Rutherford at that time was “it was about as credible as if you had fired a 15-inch shell at a piece of tissue paper and it came back and hit you”. Rutherford began examining the deflections of these alpha particles and questioned whether they were due to electric charge. In comparing his hypothesis with data acquired by Geiger and Marsden, it was confirmed to him that an atom contains a central positive charge in the nucleus.

Henry's Accomplishments

In this he showed also that this definite range, or “stopping power”, of a substance is proportional to the square root of its atomic number, and was the first to distinguish between four groups of alpha particles—those emitted by radium, radon, RaA, and RaC. Henry’s work continued with the study of the ionization of gases by alpha particles, and earned him a fellowship of the Royal Society of London. It should be noted that all of Henry’s initial work however was not all glory, as he became a center of controversy for several years concluding that X-rays and gamma rays were not electromagnetic waves, but rather streams of neutral particles. As experimental evidence arose which was in clear opposition, however, he of course adopted the new understandings. Nonetheless, Henry’s contributions had already earned him respect in the worldwide science community. In 1909, Bragg left his position at Adelaide to become the Cavendish Chair of Physics at the University of

This was called the “plum pudding model”. In 1909, Ernest Rutherford largely disproved this theory when with the help of Hans Geiger and Ernest Marsden, Rutherford found that alpha particles (two neutrons and two protons bound together) were unexpectedly deflected at angles of greater than 90 degrees when fired at metal foil. This suggested their charge was in fact not evenly spread leading Rutherford to think that the positive charge of an atom is concentrated in its centre. This was called the Rutherford Gold Foil Experiement.

Otto Hahn Research Paper

When Hahn and Strassmann bombarded uranium the element barium mysteriously appeared. Neither Hahn nor Strassmann knew what their results meant. It would take Meitner and her nephew Otto Frisch, a Jewish refugee working in Copenhagen with Niels Bohr, a few hours of work while at a ski resort to explain the mystery. Unbelievably, Meitner realized, the uranium nucleus split into two roughly equal chunks, one of which was likely to be barium. The reaction was accompanied by an enormous release of energy.
