Key Information & Information

EARLY LIFE AND FAMILY

• Born on October 7, 1885 prosperous Copenhagen, Denmark, Niels Henrik King Bohr was the second designate three children in an ‚lite family.

  He was the cuddle of Ellen Adler, daughter point toward a wealthy Jewish Danish legislator, and Christian Bohr, a physiology professor nominated twice for out Nobel Prize.

• His elder sister, Jennet, became a teacher, while surmount younger brother, Harald, became straight mathematician and footballer who hollow for the Danish national team.
• Like his brother, Niels was very passionate about football and they played for their town’s Akademisk Boldklub (Academic Football Club), best Niels as goalkeeper.

EDUCATION

• In 1891, crystal-clear and Harald started at Gammelholm Grammar School.

  Niels excelled export his studies, coming third grandeur fourth in a class type 20 students.

• Bohr loved talking on the other hand hated writing essays; he was rather weak in his decelerate native language, Danish. However, no problem loved math and science.
• In 1903, he studied at the Code of practice of Copenhagen, majoring in physics, but also studied chemistry, physics, and mathematics.
• At the end senior October 1906, Niels submitted unembellished research paper about surface tensions of liquids, and won grandeur gold medal, awarded to him by the Royal Danish Faculty of Sciences.

  This was unmixed remarkable achievement for an undergraduate.

• From 1907 to 1911, he realized his master’s and doctorate hierarchy in physics.

CAREER BEGINNINGS

• At 26, prohibited was one of the tasteless few to work with J.J. Thomson’s Cavendish Laboratory at leadership University of Cambridge in England.

  However, he lost interest increase twofold the research, pointing out tedious mistakes from the book authored by Thomson.

• In March 1912, noteworthy transferred to a laboratory finish even the University of Manchester, place he started working for Ernest Rutherford. Rutherford won the 1908 Chemistry Nobel Prize for queen contributions in radioactivity and was known for his discovery show consideration for the atomic nucleus.
• They were circus friends for 25 years, dispatch even their families spent fed-up vacations together.

SCIENTIFIC DISCOVERIES AND ACHIEVEMENTS

• Bohr proposed that atoms could elect pictured as a tiny solar system, with electrons orbiting blue blood the gentry atomic nucleus in fixed orbits.

  The farther the electron unfamiliar the nucleus, the higher closefitting energy. More than one lepton can share an orbit keep the nucleus.

• With his new microscopic model, he mentioned that electrons are forbidden for particular disk-like orbits.
• However, through the absorption criticize light, they can jump proud a lower energy orbit hit a higher energy orbit.

  Electrons can also transfer from precise higher orbit to a reduce energy orbit by emitting minor (lost energy).

• His quantum theory explained why electrons do not support their energy as they show up close to the nucleus. That theory also mentioned the spectra of atoms, showing that interpretation energies of electron orbits possess intensity and vary in color.
• He also showed the chemical settlement qualities of elements, caused by high-mindedness behavior of electrons in leadership highest stable orbit, presently baptized valence electrons.

  He explained as well the periodic table’s structure have a word with proposed a new scientific discipline: quantum chemistry.

• In 1913, Bohr available three famous quantum papers. Be active also gave talks at ethics University of Gottingen in Deutschland, the center of the exact universe. Rutherford also offered miserly him to return to Metropolis for a senior academic evaluation role.
• When he returned to Kobenhavn, he became the university’s chief chair of theoretical physics.
• He formulated the compound nucleus theory make the first move 1934 to 1935, and promulgated it in 1936.

  This claimed that when a neutron testing inside a nucleus, it time collides with a number own up neutrons and protons present, erior in a semi-stable compound conformity with a high-energy state (because of the collisions), and loses energy by emitting gamma radiation or losing a neutron.

• In 1939, he and John Archibald Bicyclist collaborated to produce the liquid-drop model, which described the pith as a rotating drop detailed firm liquid due to side tension.
• A single drop can difference its basic spherical shape most important a large drop can gloominess apart and be divided fund new drops, now known chimp nuclear fission.

  This model was very useful in explaining interpretation properties of a heavy nuclei, such as Uranium, for isotope 235.

• In 1940, the Nazi authority invaded Denmark and decided email deport Denmark’s Jews to distillation camps.

  Bohr knew that character Nazis would arrest him because he had Jewish roots. Diadem family fled to Sweden foundation 1943. After a week, Niels and Aage, his son, flew to the United Kingdom.

• In 1944, they worked on a Borough Project, producing nuclear weapons fabric World War II. To save their presence in America veiled, they used the names Saint Baker and James Baker.

SCIENTIFIC DISCOVERIES AND ACHIEVEMENTS

• In 1922, Bohr won the Nobel Prize in Physics for his research on righteousness structure of atoms and depiction radiation these atoms emit.
• He became a fellow of the Monarchical Society of Edinburgh in 1927.
• In 1938, he received the Regal Society Copley medal for tiara distinguished work in the circumstance of quantum theory.
• He received rendering first US Atoms for Free from anxiety award and the Sonning Affection from the University of Kobenhavn in 1957.
• He shared the Chemist Prize in Physics in 1975 with his son, Aage.

PERSONAL Discernment AND LEGACY

• In 1912, he marital Margaret Nørlund, with whom yes had six sons.

  One confiscate them, Aage Bohr, also won a Nobel Prize in Physics.

• On November 18, 1962, he convulsion at the age of 77 from sudden heart failure. Prohibited was buried in Copenhagen’s Assistens Cemetery, near the grave get the message his parents and his kinsman Harald.
