Compare And Contrast Thomson And Ruther

John Dalton wrote the modern atomic theory, a fundamental component of that is, the mole ratios of elements in a compound will be small whole numbers.

When someone you are attached to dies it is never easy to get over it, many times leading to become someone you are not. Hunter Jordan's sudden death that was led by a stroke not only impacted his wife Ruth, but as well as his stepson James. Even though, it was not his biological dad he saw him as a father figure. Ruth and James behaved differently after the tragic loss of their loved one.

-Henry Gwyn Jeffreys Moseley- Worked with Ernest Rutherford, experimented with 38 metals, he found that the positive charge of each element’s nucleus increased by one from element to element as they were arranged in Mendeleev’s periodic table, lead to modern definition of atomic number (# of protons in atom’s nucleus) and the recognition the

In France during the time of 1918, Henry johnson and Needham Roberts were guarding a post. Needham Roberts heard clicks, and was injured, not able to fight. Henry Johnson fought a battle of 100 germans leaving 4 dead. When Henry Johnson returned home, he was hurt and ill but still was not honored because there was segregation during that time. There was segregation between Black soldiers and white soldiers.This topic is connected to conflict and compromise because there is segregation for conflict and for compromise they finally realized blacks should have the same rights and freedom as whites.

By firing massively charged particles at an atom, he found that atoms are made up of smaller particles (Doc. 1).  This would lead to his discovery of protons also known as alpha particles (OI). After that, he bombarded gold foil and observed that some of the atoms passed through the foil. Therefore, he concluded that atoms are composed of empty space (OI).  

Scientists Who Invented the Atomic Bomb under the Manhattan Project: Robert Oppenheimer, David Bohm, Leo Szilard, Eugene Wigner, Otto Frisch, Rudolf Peierls, Felix Bloch, Niels Bohr, Emilio Segre, James Franck, Enrico Fermi, Klaus Fuchs and Edward Teller. View a copy of the letter Einstein wrote Roosevelt that prompted the Manhattan Project.

Neils Borh is another important figure because he was studying the structure. After Einstein left the Atomic bomb had been going unexpected, not to long after the first test was in New Mexico. The test was a success.

William Reiner and John Gearhart conducted an experiment where sixteen males with an inadequate or no penis were reassigned to be female. The sex change took place within two weeks of age for thirteen of the subjects, and within twelve weeks for one subject. Although they were made into anatomical girls, and were raised as girls by their respective families, most of the children did not feel feminine. At the end of the experiment, five of the subjects claimed female identity, three were unclear of their gender identity, and eight of the subjects claimed male identity. The subjects who identified as female admit that they struggle to fit in with other girls, but all subjects agree that getting along well with males is easy. They also all displayed

To touch on J. Robert Oppenheimer, it should be shown off a lot about him- he was a true genius, if you talked to him about anything besides sports, he’d be able to talk about it. He had a somewhat strange childhood- he was interested in physics since he was a young boy. It almost seemed like he knew that Uranium and Plutonium were going to make bombs. He was very intelligent, and almost always dressed like the stereotypical man at the time-

In 1913 Niels Bohr proposed a hydrogen-atom model that linked the atom’s electron to the photon emission. According to his model, electrons circle the nucleus only in allowed circuits. When the electron is in one of these orbits, the atom has a definite, fixed energy. The electron has the lowest energy state when it is in the orbit closest to the nucleus. The energy of the electron is higher as the electron is in orbits that are successively farther from the nucleus. He also discovered that an electron can be one orbit or another but not in between.

Neils Bohr was born in 1885 in Denmark. He went to the University of Copenhagen where he studied physics. In 1911 he got his Ph.D. Neils presented the fact that the fission chain reaction need u-235 to be possible. He fled and went to America to work on the Manhattan Project. Bohr wanted people to know that the effects of nuclear bombs were good and bad. He asked the UN to rid themselves of nuclear weapon Projects. He later died in November 1962.

Thomson4 discovered the electron3 using a cathode ray4. In a cathode ray an electric current is passed through a discharge tube5 which causes a glowing light that, Thomson concluded, was made up of smaller particles. He then discovered that these particles had a negative charge and were actually electrons. Thomson knew that electrons had a negative charge and believed that matter must have a positive charge as well. From the knowledge he accumulated, he formed a model of what he believed the structure of the atom looked like. This model has come to be known as the Plum Pudding Model4. In 19004 a professor of theoretical physics, Max Planck4, discovered that when you vibrate atoms strong enough you can measure the energy. Planck called these packets of energy quanta. At the time, physicists believed that light consisted of waves. Albert Einstein4 concluded that the quanta behaved like discrete particles. For many years there was a controversy on whether light consisted of waves or particles. In 1911 Ernest Rutherford4 bombarded atoms with alpha rays. Rutherford used Radium as the alpha particles4 and shined them onto gold foil. This was called the Gold Foil Experiment4. The conclusion from this experiment was that positively charged matter scattered the alpha particles and that most of the space4 around these positively charged centers has nothing in it. Furthermore, Rutherford thought that electrons must exist somewhere within that empty space and that they orbited a positive center, like the planets orbit around the sun. Rutherford also speculated that atoms consisted of a compact positively charged nucleus4 as well as that most of the atom’s mass is contained in the nucleus. In 1919 Rutherford finally identified the particles of the nucleus as discrete positive charges of matter and named them protons4. He developed a model of the atom but, due to the theory of electricity and magnetism, it was predicted, according to this model,

Other scientists like J.J. Thomson helped develop the overall knowledge of chemistry, especially with his discovery about the first subatomic particle, the electron, in 1897. However, despite Thomson’s important breakthrough, Bohr’s discovery in the early 1900’s developed a strong basis and knowledge about the entire atom’s appearance and what it contained which made a significant impact on chemistry. Bohr’s innovation was published as a model that established the theory of electrons moving in orbits around the nucleus of the atom. He also introduced the idea of the chemical properties of the element being mostly governed by the number of electrons located in the outermost orbits. It can be argued that discovering the electron itself before Bohr’s research is more important to his own discovery, but without his new discovery, the theory of electrons wouldn’t have been determined later along with the base principles of electrons and how they interact. Furthermore, any knowledge about the electron cloud would be compact without pivotal knowledge of what an atom looks

Ernest Rutherford was a New Zealand born British physicist who is famously known for “splitting the atom.” His work on the gold foil experiment contributed greatly to the model of the atom and helped develop the standard model of the atom to what we now use today. Without his contributions we would still be using the Plum Pudding model, an out dated and incorrect model, and we would have less of an understanding of how atoms form the world around us.

Later on in the 20th century came a man named Earnest Rutherford. This physicist conducted an experiment that is widely known in the chemistry world: the gold-foil experiment. The experiment went like this: there was an alpha particle source that would pass through gold foil in a vacuum. The outcome of this experiment was that the particle went through, but went in different directions. This forced Rutherford to conclude that an atom was much more than just open space with scattered electrons, showing that Thomson’s “Plum Pudding Model” to be inaccurate. Rutherford had also concluded that an atom must have a positively charged center that contained most of it’s atomic mass. Rutherford was a major contribution to chemistry, discovering the nucleus and the proton.
