Bohr Model
"Prediction is very difficult, especially about the future".
The words are by Niels Bohr, the father of the atom as we know it. A Man of Many Interests I. Niels Bohr, ironically known as 'the Pope' among his colleagues, was born in 1885, in Copenhagen, where he lived for most of his life. He created the Institute for Theoretical Physics, now known as the Niels Bohr Institute, where he mentored and collaborated with the best scientists of his time. II. Bohr’s interests ranged from philosophy to soccer. He was influenced by the work of Søren Kierkegaard and usually played as a goalkeeper. But the family’s football star was his younger brother Harald, who played in the Danish national team and won the silver medal at the 1908 Summer Olympics. III. Niels Bohr had six children. One of them, Aage, was awarded the physics Nobel Prize in 1975. IV. Bohr believed in the importance of sharing knowledge about nuclear research. In 1950 the United Nations, following his suggestions, created the International Atomic Energy Agency (IAEA). Bohr and the Atomic Model
Niels Bohr's model of the hydrogen atom—first published 100 years ago and commemorated in a special issue of Nature—is simple, elegant, revolutionary, and wrong. Well, "wrong" isn't exactly accurate—incomplete or preliminary are better terms. The Bohr model was an essential step toward an accurate theory of atomic structure, which required the development of quantum mechanics in the 1920s. Even in its preliminary state, the model is good enough for many calculations in astronomy, chemistry, and other fields, saving the trouble of performing often-complex calculations with the Schrödinger equation. This conceptual and mathematical simplicity keeps the Bohr model relevant.
Despite a century of work, atomic physics is not a quiet field. Researchers continue to probe the structure of atoms, especially in their more extreme and exotic forms, to help understand the nature of

    Six scientists were chosen to see which one had made the greatest contribution to our current understanding of the atom’s structure. Our knowledge of an atom’s appearance and structure have evolved from years and years of development and contribution from many different scientists. Scientist Ernest Rutherford had been the best contributor to the understanding of the atomic structure. Why Rutherford was chosen is because his work had information on protons, neutrons, and electrons, the main components that make up the atom, showed what the atom looks like when the three are put together, and had also been the discoverer of the nucleus which is the one of them most important parts of the atom’s structure.…

Each evaluated and revised the atomic theory over the years to incorporate new findings such as, the existence of atomic isotopes and the conversion of mass and energy. Although over several decades many have changed the atomic theory, Dalton still has an impact and his importance is relevant in the development of the atomic…

    The quantum theory began in 1900; while the first initial commencement of studies was made when Max Planck suggested that energy is quantized. Progression has been made continuously to this theory from a variety of other scientists including Albert Einstein. Planck has successfully discovered a theory to provide an accurate outcome, becoming a more intelligent choice of study over the well-established Newton’s Law. Still to this day Max Planck’s quantum theory is the most advanced source of scientific studies on subatomic…

    The Manhattan Project may have never come to fruition if it wasn’t for that one German physicist: Otto Hahn. Hahn, working with Fritz Strassmann, discovered that when uranium was bombarded with neutrons a radioactive barium isotope was among the products. Hahn immediately realized the importance of this and told one of his colleagues (who had fled Germany due to nazi racial laws), Lise Meitner, about his findings. Lise worked with her nephew Otto Frisch to replicate Hahn’s findings and conclude that fission had taken place. The duo immediately made their way to Copenhagen to tell Bohr of their theories. Bohr was soon to be in the United States at Princeton’s Institute for Advanced Study. (Hewlett and Anderson,…

    In 1913, a Danish physicist named Niels Bohr put Rutherford's findings together with the observed spectra to come up with a new model of the atom in a real leap of intuition. I believe that the Bohr’s model of atom explains well about the atomic theory, because in his experiments it is shown and explained the structure of an atom. His famous suggestion is about that the electrons orbit around the nucleus of an atom. Bohr experimented with atomic spectrum that proved his suggestion.…

    The Gold Foil Experiment

    Ernest Rutherford’s Gold Foil Experiment was a major stepping stone one the way to discovering what the atom was really made up of. From the beginning of his research with alpha particles to his discovery of the atomic nucleus, Rutherford made many contributions to the microscopic world of the atom. The Rutherford Experiment, otherwise known as the Gold Foil Experiment, was the crown of his achievements, and it was during this experiment that he discovered the atomic nucleus. (Aydin &Hanuscin, p.59) He made this happen by putting his past research on alpha particles to the test, such as the knowledge that an alpha particle should be less massive than the atom. Therefore the alpha particles should pass directly through the atom, unfazed. When the particles started to reflect off of the atoms in obtuse angles, Rutherford began to question the plum pudding model of the atom. It did not take him long to scientifically prove the model wrong, it only took about 2 years after the initial experiment to get enough proof to disprove the Plum Pudding Model and publish his own atomic model, The Rutherford Model. This article will be focusing on Rutherford’s Gold Foil experiment and how the experiment’s results changed how scientists would look at the structure of the atom for many years to come.

    One argument against continuing research on the atom is that the cost continues to increase at an alarming rate, and the benefits seem to be declining. Wheras quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results, now very few if any practical results are emerging, but the costs of experiments continues to increase. For example, the Large Hadron Collider(LHC) was recently constructed for the sole purpose of studying the behavior of atoms under extreme conditions. The final cost of the LHC was somewhere around $9 BILLION, and has yielded no practical results, nor promises to do so in the future. Contrast this to 80 years ago, when the field of quantum chemistry was just emerging. The results provided during the early and mid 1900s such as the Schrödinger equation and Heisenberg uncertainty principle enable virtually everything chemistry related today. The fields of pharmaceutical chemistry and polymer science(plastics especially) would still be in their infancy if not for the work on quantum mechanics during this time. These major accomplishments were largely based on complex derivations and rarely had experiments that cost a significant sum.…
