Ernest Rutherford Research Paper

He discovered many helpful uses for atomic energy. He created the world’s first nuclear submarine named the USS Nautilus. All his work helped to expand the American nuclear fleet that included fifty three submarines and surface ships.

According to DePra’s poem, “The electron is minus, the proton is plus,/ the neutron is neither” (Doc. 2). In other words, a neutron is neutral, the electron is negative and the proton is positive. After these discoveries, more inventions were made to help further our understanding of atoms, for instance, the the electron microscope. Electrons were discovered before Rutherford by JJ Thomas (OI). Thomas was using a cathode ray and discovered that atoms are made of smaller subatomic particles

Enrico Fermi (1901-1954) succeeded in splitting the uranium atom and the Nobel Committee later awarded him the 1938 prize for physics. At Columbia

One of the scientists that was involved was Enrico Fermi. Fermi was the first to make contact with the U.S. about the Germans starting to experiment with fission. Then Albert Einstein, who was a German physicist who escaped Germany to come to the U.S., eventually persuaded President Franklin D. Roosevelt to start a program around nuclear fission to combat German efforts. Additionally, American scientist Philip Hauge Abelson created a uranium separation process that was necessary is making the atomic bomb.

Before the Manhattan Project, in the beginning there were many advancements in understanding made in the world of physics. These resulted in the recognition of nuclear fission and its potential as an energy source and as a potential weapon. Of these advancements none was more central and important than the development of the nuclear model of the atom, which by the year of 1932 contained a nucleus containing most of the mass of an atom in the form of two particles, protons and neutrons. This nucleus was surrounded by an electron shell. Previously it was thought that atoms were the smallest form of matter therefore ultimately stable and indivisible. However, in 1919 Ernest Rutherford was able to break apart the nucleus of nitrogen with

During the early 1940’s atomic science had just began to mature. Many people were exploring the powerful mystery of the atom. Two of those people were Eugene Booth and John Dunning, who, in 1941, synthesized uranium-235. Immense scientific growth followed their contribution, since it allowed for nuclear fission (Griffith). In the years following this discovery, nuclear science took a turn. Once only used as a constructive power source, atoms began being explored for their destructive power. In 1942 the United States government funded the Manhattan Project that sole goal was to develop a nuclear bomb. The initiator for this endeavor was surprisingly the famous scientist Albert Einstein. He wrote to Franklin D. Roosevelt , and tipped him off

This is what led Curie to take Becquerel’s work a few steps further and conduct her own experiments on uranium rays. She discovered that the rays were constant no matter what form or condition of the uranium. She theorized the rays came from the atomic structure. This idea was revolutionary and created its own field in science, known as the atomic physics, this is when Marie coined the word “radioactivity” to describe the phenomena. Even when they had their first daughter Irene in 1897 there work did not slow. Pierre then stopped his own studies to help Marie with her new discovery of radioactivity. In 1898 they discovered a new radioactive element. They named it polonium after Marie’s native country, Poland. They detected the presence of another radioactive element and called this radium. In 1902 they had extracted pure radium to prove its existence as a unique chemical element.

The pioneering work of Becquerel in 1896 (the discovery of uranium), and the Curies (who subsequently discovered radium and polonium and the energy and heat given off by these new elements which they called radioactivity) led to the remarkable work of Ernest Rutherford. He was a physicist, whose experiments showed that some heavier elements spontaneously changed or decayed into lighter elements (unstable 'parent' elements giving off protons and neutrons to form a 'daughter' element) through the process of radioactivity. He discovered that radioactive materials decay at a very predictable rate, and that lead was the final decay product of uranium. Using Rutherford's ideas, Bertram Boltwood pioneered a method of radiometric dating in 1907. He hypothesized that since he knew how long it takes uranium to break down, he could measure the proportions of lead in uranium ores, and use his calculations to date how long those ores had existed,

Both Albert Einstein and Ernest Rutherford helped pave the way for countries to invent the nuclear weapon. Einstein’s Theory of Special Relativity and Rutherford’s discovery of the atomic nucleus all helped the United States to invent the bomb. In the book by Andrew Futter, the United States began their experimenting on nuclear weapons with the Manhattan Project. The Manhattan Project- so called because the initial headquarters were on the Manhattan district of New York City- began in 1942 with the sole purpose of creating an atomic bomb before Nazi Germany. (Futter 17) Work on the project was spread out all over the country; the main research center would be located at Los Alamos in the New Mexico desert. There were two lines of research,

His 3 papers, which later became famous as the “trilogy “were published in the Philosophical magazine in July. Later in the year He revised Rutherford’s nuclear structure to Max Planck’s quantum theory and created the Bohr model of the atom. He revolutionized the theory of electrons traveling in orbits around the atoms nucleus. He also announced the idea that an electron could drop from a higher energy orbit to a lower one, in the progress also emitting a quantum of discrete energy. This theory became known as the old quantum theory. The trilogy’s acceptance was dur to it s ability to explain the phenomena which blocked other models ,and predicted the results that were then verified by experiments. Today the Bohr model of the atom has been outdated but is still known as the best model of atoms, and is still used in high school physics and chemistry.

His discovery to radioactivity helped a lot of other scientists. If Henri hadn't discovered it Ernest Rutherford

Niels Bohr led an interesting life, and left a noble legacy behind. Although his atomic model isn’t the most accurate, it is still very globally used, Bohr also has the honor, of having an element, Bohrium, after him. If he was alive today, he would likely want to know how he influenced the physics community. In conclusion, Bohr is a gifted, multi-awarded person, who changed everything we knew. Like Bohr said, “An expert is a person who has made all the mistakes that can be made in a very narrow

Bohr was one of the fortunate scientist to have been born in a period to where concepts of the atomic theory have been discovered. Such as the discovery of an electron by J.J. Thomson(when Bohr was 12), Albert Einstein’s ‘barrage of new ideas’ in 1905(Bohr being at the age of 19, working on his gold winning research), as well as the discovery of the atomic nucleus, by Ernest Rutherford(when Bohr was at the age of about 23). All of these discoveries, were the key to developing Bohr’s interest and curiosity to evaluate them through with the scientists themselves.

Ernest Rutherford's model of the atom is one of the oldest around. Although it is not considered accurate today, it was a huge advance for figuring out the complexity of Atoms.  Rutherford's atom illustrates that atoms revolved in empty space with electrons orbiting a fixed position of positively charged nucleus and had a predictable set path. Ernest was a New Zealand native working at the University of Manchester in the early 1900s. He spent most of his time and career researching the aspects of radioactivity, and in 1908 received the Nobel Peace Prize for his accomplishments. It was another several years after when he started his research on atoms.

He proposed that under certain circumstances light could be considered a particles. He also hypothesized that the energy carried by a photon is depositional to the frequency of radiation. The formula E= HU proves this. Virtually no one accepted this theory but thought differently when Robert Andrews Millikan proved it.
