Recommended: Write an essay on the Bohr's atomic model

In 1899, Rutherford had hypothesized an atomic model, which he described the hydrogen atom as a small, heavy, and dense nucleus. Electrons were placed on the outside of the atom. Neils Bohr proposed his atomic model in 1913. Bohr adapted the Rutherford model by requiring that the electrons exist in different energy levels, but only certain amounts were possible. So the electrons were narrowed to definite orbits. Therefore, Bohr improved Rutherford’s atomic model by saying that electrons travelled in round orbits with specific energy levels. The Bohr’s models main principles are, “1.) The electron in a hydrogen atom travels around the nucleus in a circular orbit. 2.) The energy of the electron in an orbit is proportional to its distance from

Thomson of the negatively charged electron implied that a neutral atom must also contain an opposite positive charge. In 1903 Thomson had suggested that the atom was a sphere of uniform positive electrification , with electrons scattered across it like plum in an pudding. (Later known as the Plum Pudding Model)

    Development of the Hydrogen Bomb In the world, there is little thing called power. Many countries want to have great power, few get it. Powers gave the Soviet Union and the U.S. the ability to dominate in wars. In the 1950’s during the Cold War these two countries had a race to see who could create the most powerful weapon the world has ever seen, the Hydrogen Bomb. Edward Teller, an atomic physicist, and Stanislaw Marcin Ulam, a mathematician, "who together developed the Teller-Ulam design in 1951" for the Hydrogen Bomb (Teller-Ulam Design).

    In 1939, the scientific world had discovered that Germany was building an atomic bomb. Albert Einstein had fled german prosecution earlier in his life. Upon hearing of Germany’s knowledge of splitting an uranium atom, he felt he must inform President Roosevelt about this. Roosevelt didn’t see the need in the atomic bomb but agreed to it anying. The code name for the atomic bomb was The Manhattan Project. Columbia University, the University of California at Berkeley, and the University of Chicago started the research for the atomic bomb. Enrico Fermi led a group of physicists to create the first controlled nuclear chain reaction underneath Stagg Field. Stagg Field was the University of Chicago’s football field. Here is where the first controlled

  • Niels Bohrs Model Of The Hydrogen Atom

    361 Words  | 1 Pages

    Niels Bohr's model of the hydrogen atom, was the primary reason for the understanding of energy levels.Bohr was able to explain the bright line spectrum of hydrogen. Sparked by the recent discovery of the diffraction patterns, scientists believed electrons could be described as waves. Bohr hypothesized that energy is being added to the hydrogen gas in the electricity form, and then leaving the gas in the form of light. He figured the light rays to be quantized, meaning only certain frequencies of the light rays can be seen. In turn, he reasoned that the hydrogen atoms themselves were quantized and, that they only can exist in certain energy levels. When the atoms absorb specific amounts of energy, they exist for a small period of time in higher energy levels. But as soon as these atoms lose their energy, they move back down to the lower levels of energy. His theory went on to state how the hydrogen atom can move up and down the energy levels, one level at a time, and can never stop in between. Every hydrogen atom is made up of a single electron - proton system. Because the negative electron is attracted to the positive proton, potential energy is created inside the atom.He figured that the farther away the electron is from the proton, the greater the potential energy is inside. In conclusion, since hydrogen atoms emit light energy in specific frequencies, the hydrogen atom must be within a specific energy level and nothing else. The different wavelengths help to determine the different colors emitted from the atom. The greater the wavelength, the faster the atom can be filled and jump to a higher level.Bohr developed his theory after studying the work of Einstein's ideas on the photons of energy.

    Bohr was born on October 7, 1885 in Copenhagen, Denmark to Ellen Adler and Christian Bohr. Eventually, Niels Bohr graduated from Copenhagen University with his masters in physics. That same fall in 1911, Bohr traveled to Cambridge, England and worked alongside scientist J.J Thompson. Through Niels Bohr’s professional life he was able to construct a revolutionary theory on the atomic structure. His work would lead him to win the Nobel Prize in 1922 in physics for his great contribution. Yet, one of the most controversial things Bohr participated in was the debates between Albert Einstein and himself. Both were hugely renowned physicists, each with their own credentials and ideas. Therefore, this led to a clash of ideas. The debate began over the different beliefs surrounding quantum mechanics. So after many public debates, Bohr was ruled victorious in defending his stand on the idea. The victory didn’t build any hostility between the two major scientists, as they continued to be good friends after the incident. Niels Bohr is a perfect example of the people Einstein would associate with, he was a genius with a legacy that he left

    The atom, the basic building block of matter, consists of a core nucleus surrounded by negatively charged electrons. Inside the atom nucleus contains a mixture of positively charged protons, and electrically neutral neutrons. All atomic electrons bind to the nucleus through electromagnetic force. A ground of electrons bound together will form individual molecules. An atom with an equal number of protons and electrons will hold neutral. An ion has positive or negative charge, either through a lack of electrons or an electron excess. The number of protons determines the formation of chemical elements, while as the number of neutrons determines the element's isotope. Most of the atom's mass has a concentration compacted within its nucleus; however, protons and neutrons hold about the same mass. Electrons bound to atoms hold a percentage of stable energy levels, otherwise known as orbitals, which undergo transitory processes through absorbing or omitting photons with equal energy levels. Electrons determine an element's chemical properties, thus influencing an atom's magnetic properties.

    His father was Christian Bohr, who won a Nobel Peace prize. His mother was Ellen Adler, daughter of a wealthy Danish politician. Niels’ parents were passionate about their children’s education. Niels was taught at home until he started formal schooling aged 7 at the Gammelholm Grammar School. The school had strict discipline and expected its students to work hard. Bohr knew that Rutherford’s picture of the atoms isn’t match with the laws of classical physics. These held that negatively charged electrons must be pulled into the positively charged nucleus. He wrote his Ph.D. thesis that said it was impossible for classical physics to explain behavior at the atomic scale. Quantum physics had established that when an object radiates heat or light waves, the emission comes not in a continuous stream, but rather in distinct packets of wave energy. Like all waves, photons have a speed, frequency and a wavelength. Bohr’s new model of the atom gave a reason as to why scientists had wondered how matter could absorb light. He found that electrons are restricted to particular circular orbits, but can jump from a lower energy orbit to a higher energy orbit by absorbing

    To start off, learning the Bohr-Rutherford diagrams in grade nine was a very big confusion for me. I had never fully understood how many shells should go around the nucleus nor did I know how to do the many calculations. As I progressed into grade ten, the teachings became easier. The review shows an example such as in the the bohr diagram, a nucleus is in the center, which is a little circle, and following that there are shells surrounding it containing electrons. Each ring can only hold a certain amount of electrons, and so the first shell around the nucleus can hold a maximum of 2 electrons, the next shell is able to hold a maximum of 8 electro...

Atoms of different elements may also combine into systems called MOLECULES, which are the smallest units of chemical COMPOUNDS. In all these ordinary processes, atoms may be considered as the ancient Greeks imagined them to be: the ultimate building blocks of matter. When stronger forces are applied to atoms, however, the atoms may break up into smaller parts. Thus atoms are actually composites and not units, and have a complex inner structure of their own.
