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

Over the years there have been many scientists studying the atom and making huge discoveries. Although all of them have been on the right path, Niels Bohr was credited with having the most correct atomic model and electron mechanics until recently. Coming from a very educated background, Bohr came up with his atomic theory which corrected Rutherford's atomic theory. His discovery made a huge impact on what everyone else thought about the atom and left a very complete and thorough explanation of the atom.

Who was Niels Bohr?

Niels Bohr was a Danish physicist who lived from 1885 to 1962. He was the third child of Christian Bohr and Ellen Adler Bohr. He was very close to his brother Harald. He was greatly influenced by his father, who was a physiology professor at the University of Copenhagen, which Niels later attended. His father often met with scholarly men and Bohr was present for most of those meetings. He also participated in the Royal Danish Academy of Sciences and Letters which was what first got him interested in the atom. His interest in the atom continued after doing...

    Alfred Nobel was born in Stockholm on October 21, 1833. By the age of 17 he was fluent in Swedish, Russian, French, English and German. Early in his life he had a huge interest in English literature and poetry as well as in chemistry and physics. Alfred's father disliked his interest in poetry and found his son rather introverted. In order to widen Alfred's horizons his father sent him to different institutions for further training in chemical engineering. During a two-year period he visited Sweden, Germany, France and the United States. He came to enjoy Paris the best. There he worked in the private laboratory of Professor T. J. Pelouze, a famous chemist. He also met the young Italian chemist Ascanio Sobrero who, three years earlier, had invented nitroglycerine.

    Similar examples can be found in physics. Prior to the Michelson-Morley Experiment of 1887, which showed the constant speed of light, the experiments of FitzGerald and Lorentz, which explained the constant speed of light as the contraction of bodies and slowing of clocks, and the subsequent conclusion by Einstein that electromagnetic waves do not require a medium, scientists felt that light required a medium, and thus one was invented-ether (Hawking). These experiments demonstrate yet another aspect of a personal point of view in the pursuit of knowledge; the fact that despite the assumptions a personal point of view brings into a study, such as FitzGerald’s and Lorentz’s assumption that ether did, in fact, exist, knowledge can still be gained from such a study. Despite their assumption, they contributed, through their experiments, the knowledge that light does travel at a set speed. Thus, even when associated with false assumptions brought into an experiment, personal points of view are not always negative.

    Oppenheimer was the son of a German immigrant who had made his fortune by importing textiles in New York City. During his undergraduate studies at Harvard University, Oppenheimer excelled in Latin, Greek, physics, and chemistry, published poetry, and studied Oriental philosophy. After graduating in 1925, he sailed for England to do research at the Cavendish Laboratory at the University of Cambridge, which, under the leadership of Lord Rutherford, had an international reputation for its pioneering studies on atomic structure. At the Cavendish, Oppenheimer had the opportunity to collaborate with the British scientific community in its efforts to advance the cause of atomic research. Max Born invited him to Göttingen University, where he met other prominent physicists, such as Niels Bohr and Paul Dirac, and where, in 1927, he received his doctorate.

  • What Is Quantum Mechanics Essay

    887 Words  | 2 Pages

    In 1907, Einstein used Planck’s hypothesis of quantization to explain why the temperature of a solid changed by different amounts if you put the same amount of heat into the material. Since the early 1800’s, the science of spectroscopy had shown that different elements emit and absorb specific colors of light called “spectral lines.” In 1888, Johannes Rydberg derived an equation that described the spectral lines emitted by hydrogen, though nobody could explain why the equation worked. This changed in 1913 when Danish physicist Niel Bohr applied Planck’s hypothesis of quantization to Ernest Rutherford’s 1911 “planetary” model of the atom, which affirmed that electrons orbited the nucleus the same way that planets orbit the sun. Bohr offered an explanation for why electrical attraction does not make the electrons spiral into the nucleus. He said that electrons in atoms can change their energy only by absorbing or emitting quanta. When an electron absorbs a quantum it moves quickly to orbit farther from nucleus. When an electron emits a quantum the electron jumps to a closer

  • Essay On The Periodic Table

    871 Words  | 2 Pages

    Attempts to organize the elements began in the late 1800’s. At this time, about sixty elements were known. Much advancement would have been impossible if the basic model of the atom was discovered. Great progress came from Dmitri Medeleev – a Russian chemist. His first draft of a periodic table was only the product of him attempting to summarize his knowledge of the elements. Although not all of Medeleev’s ideas were one-hundred percent accurate, they created a solid base to build upon. Marie and Pierre Curie; a married couple from Paris were successors of Medeleev. Their interests were radioactivity and discovered radium. The true pioneers of the periodic table were Ernest Rutherford and James Chadwick. Rutherford formed the hypothesis that, “An atom must have a concentrated positive center charge that contains most of the atom’s mass.” Following Rutherford, Chadwick exposed a segment of the nucleus that was had no charge: the neutron. With the basic knowledge of the structure of an atom, the tedious work of putting the rest of the puzzle together continued.

    The Atomic Theory began in roughly 400BC with Democritus in Ancient Greece and is universally believed to be correct today. Democritus who was born in 460 BC and died 370 BC and is known as the father of modern science. Democritus proclaimed that everything is made up of atoms. He continued his theory to say that atoms will always be in motion, between atoms there is empty space, atoms are unbreakable, there are an infinite number of atoms all different sizes and shapes. He also said that iron atoms are solid and strong and have hooks to lock them together, water atoms are smooth and slippery, salt atoms have sharp jagged edges because of its taste and air atoms are light and spiralling.

    I feel personally that the discovery of the atom was an important discovery for the world. With the discovery we are now able to answer questions we never even thought to ask. We are also answering questions some people asked long ago. We can now use our vast knowledge of the atom to measure the stars and be able to tell you what the stars are made of. The atomic discovery also helped us find our periodic table of elements. The periodic table of elements is a huge scientific chart that shows important facts with the help of its formation. There was a lot of constant scientific research that went into making the periodic table of elements and what it is today.

  • Atomic Energy

    1685 Words  | 4 Pages

    Scientists from earlier times helped influence the discoveries that lead to the development of atomic energy. In the late 1800’s, Dalton created the Atomic Theory which explains atoms, elements and compounds (Henderson 1). This was important to the study of and understanding of atoms to future scientists. The Atomic Theory was a list of scientific laws regarding atoms and their potential abilities. Roentagen, used Dalton’s findings and discovered x-rays which could pass through solid objects (Henderson 1). Although he did not discover radiation from the x-rays, he did help lay the foundations for electromagnetic waves. Shortly after Roentagen’s findings, J.J. Thompson discovered the electron which was responsible for defining the atom’s characteristics (Henderson 2). The electron helped scientists uncover why an atom responds to reactions the way it does and how it received its “personality”. Dalton’s, Roentagen’s and Thompson’s findings helped guide other scientists to discovering the uses of atomic energy and reactions. Such applications were discovered in the early 1900’s by using Einstein’s equation, which stated that if a chain reaction occurred, cheap, reliable energy could b...
