Recommended: History of science and technologies

Every since the beginning of history, scientist have been making many advancements. Science can be so complex and is constantly being readjusted due to learning new knowledge. Scientists, John Dalton, J.J. Thomson, and Niels Bohr, are just a few who have contributed to our modern understanding of an atom.

John Dalton was born on September 6, 1766, in England, UK. He was an intelligent child, who took part in society around him. He always tried to learn as much as he could about everything.Dalton attended a school in his village. After age 11 he began helping as a teacher.
When he was 15 , he started helping his older brother John to run a boarding-school. John continued teaching himself science, mathematics, …show more content…

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

As a member of the Continental Congress, Carroll was one of the singers of the Declaration of Independence in 1776. In fact, He also helped to write Maryland’s Constitution of 1776.

  • 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.

    Niels Bohr was born on October 7, 1885, in Copenhagen Denmark. He was born into an upper middle-class family. His father, Christian, was a professor of physiology at the University of Copenhagen. His father also was nominated twice for the Nobel Prize in physics. His Father’s ambitions in physics sparked Niels Bohr’s interest in physics. Niels Bohr received his master’s degree in physics in 1909 from the University of Copenhagen and then achieved his doctor’s degree in 1911. He became a professor at the University in 1916, and then founded the university’s Institute of Theoretical physics in 1921. His mother, Ellen, was the daughter of a prominent-Jewish banker. Niels Bohr’s Jewish decent caused him many issues in his research in Europe during World War II.

  • Life of John Dalton

    He was born in Eaglesfield, Cumberland (now know as Cumbria). In school he was so successful that at the age of 12 he became a Teacher. In 1785 he became one of the principles and in 1787 he made a journal that was later made into a book, describing his thoughts on mixtures of gases and how each gas acted independently and the mixtures pressure (which is the same as the gases volume if it had one). Therefore the law of partial pressures was made. It is said that in 1790, Dalton?s aims were to pick up in law or medicine, but he got no encouragement from his family. In 1793 he moved to Manchester where he was appointed Professor of Mathematics and Natural Philosophy at a Dissenting New College. He stayed there until 1799 when he made his own academy.

    Physicist today have been experimenting with atoms to find out more about what they do. One atom they have been experimenting with is the Higgs Boson that can be found in the Large Hadron Collider. As Abigail Beal wrote, “By smashing particles together at high speeds, to create high-energy collisions, particle accelerators were first used to look into the structure of an atom’s nucleus” (Wired UK). Physicist are experimenting with atoms to find out all they are capable of. When they are able to find out what all they are capable of, it will unlock great things in science. When Democritus came up with the theory of atoms being the basic building block of nature, he most likely didn’t think by this point in time one of his greatest ideas would be an instrumental part of

  • Important Discoveries in Chemistry

    1050 Words  | 3 Pages

    An important discovery in Chemistry is the Atomic Theory, John Dalton linked invisible atoms. Dalton’s atomic theory was based on the belief that atoms could be dignified by the differences in their masses. He first stated his theory in 1803 at the Royal Institution, the theory had six basic ideas : all matter is composed of atoms, atoms cannot be made or destroyed, all atoms of the same element are identical, and different elements have different types of atoms. Atomic Theory didn’t start with though John Dalton in fact it started with Democritus dating all the way back to about 460 B.C.. He believed that there were small invisible bodies from which everything is made of and travels in a void of space. He also rationalized the different laws of chemical combination during this time. Many, many, many years later in 1704 Newton came along and proposed a mechanical with small solid masses and that forces held atoms together. In 1803 Dalton said that, “All matter is composed of atoms and that they can’t be created nor destroyed, atoms of the same element are identical, chemical reactions can happen when atoms are rearranged and compounds are created from atoms of elements. His theory explained things that were unclear at the time. In 1894 G.J. Stoney put out the idea that electricity was form of electrons. He started the idea of using symbols to represent the elements and he contributed to finding out the exact atomic weight. Later on in 1897 J.J. Thomson used a CRT to experimentally find out the charge of an electron. He did this by multiplying 1.79 by 10 8. In 1900 Planck used the idea of quanta to clarify hot glowing matter. In 1903 Nagaoka suggested a “Saturnian” model of atoms with flat rings of electrons circli...
