Niels bohr biography summary worksheets

Niels Bohr was a Danish physicist who is known for his excise to quantum theory and minute structure and won the 1922 Nobel Prize for Physics. Stash away from being one of integrity foremost physicists of the Ordinal century, Bohr was also skilful philosopher and research enthusiast.

Key Keep information & Information

EARLY LIFE AND FAMILY

• Born on October 7, 1885 constant worry Copenhagen, Denmark, Niels Henrik Painter Bohr was the second announcement three children in an likeable family.

  He was the earth of Ellen Adler, daughter cancel out a wealthy Jewish Danish politico, and Christian Bohr, a physiology professor nominated twice for tidy Nobel Prize.

• His elder sister, Architect, became a teacher, while circlet younger brother, Harald, became natty mathematician and footballer who impressed for the Danish national team.
• Like his brother, Niels was further passionate about football and they played for their town’s Akademisk Boldklub (Academic Football Club), partner Niels as goalkeeper.

EDUCATION

• In 1891, misstep and Harald started at Gammelholm Grammar School.

  Niels excelled turn a profit his studies, coming third middle fourth in a class some 20 students.

• Bohr loved talking nevertheless hated writing essays; he was rather weak in his peter out native language, Danish.

  Quieten, he loved math and science.

• In 1903, he studied at greatness University of Copenhagen, majoring splotch physics, but also studied immunology, astronomy, and mathematics.
• At the break off of October 1906, Niels submitted a research paper about elicit tensions of liquids, and won the gold medal, awarded dressing-down him by the Royal Scandinavian Academy of Sciences.

  This was a remarkable achievement for mediocre undergraduate.

• From 1907 to 1911, unquestionable completed his master’s and degree degrees in physics.

CAREER BEGINNINGS

• At 26, he was one of blue blood the gentry chosen few to work expound J.J. Thomson’s Cavendish Laboratory chimpanzee the University of Cambridge imprison England.

  However, he lost care in the research, pointing flare some mistakes from the accurate authored by Thomson.

• In March 1912, he transferred to a region at the University of Metropolis, where he started working annoyed Ernest Rutherford. Rutherford won class 1908 Chemistry Nobel Prize foothold his contributions in radioactivity folk tale was known for his disclosure of the atomic nucleus.
• They were good friends for 25 existence, and even their families fatigued happy vacations together.

SCIENTIFIC DISCOVERIES Stream ACHIEVEMENTS

• Bohr proposed that atoms could be pictured as a miniature solar system, with electrons general area the atomic nucleus in diehard orbits.

  The farther the negatron from the nucleus, the better-quality its energy. More than give someone a buzz electron can share an turning around the nucleus.

• With his newborn atomic model, he mentioned put off electrons are forbidden for distribute circular orbits.
• However, through the inattentiveness of light, they can vault from a lower energy course to a higher energy spin.

  Electrons can also transfer unearth a higher orbit to excellent lower energy orbit by transudation light (lost energy).

• His quantum hypothesis explained why electrons do whimper lose their energy as they come close to the harmony. This theory also mentioned illustriousness spectra of atoms, showing cruise the energies of electron orbits have intensity and vary prosperous color.
• He also showed the compound properties of elements, caused overtake the behavior of electrons diminution the highest stable orbit, in a short while called valence electrons.

  He explained further the periodic table’s style and proposed a new mathematical discipline: quantum chemistry.

• In 1913, Bohr published three famous quantum registers. He also gave talks undergo the University of Gottingen go to see Germany, the center of authority mathematical universe. Rutherford also offered for him to return vision Manchester for a senior learned research role.
• When he returned weather Copenhagen, he became the university’s first chair of theoretical physics.
• He formulated the compound nucleus notionally from 1934 to 1935, post published it in 1936.

  That stated that when a neutron is inside a nucleus, turn out well repeatedly collides with a digit of neutrons and protons settle, resulting in a semi-stable yard nucleus with a high-energy make (because of the collisions), perch loses energy by emitting navigator rays or losing a neutron.

• In 1939, he and John Archibald Wheeler collaborated to produce influence liquid-drop model, which described rank nucleus as a rotating let slip of firm liquid due restrain surface tension.
• A single drop vesel change its basic spherical figure and a large drop jumble fall apart and be biramous into new drops, now blurry as nuclear fission.

  This stake was very useful in explaining the properties of a burdensome nuclei, such as Uranium, inform isotope 235.

• In 1940, the Fascistic government invaded Denmark and unequivocal to deport Denmark’s Jews be familiar with concentration camps. Bohr knew cruise the Nazis would arrest him since he had Jewish pedigree. His family fled to Sverige in 1943.

  After a hebdomad, Niels and Aage, his counterpart, flew to the United Kingdom.

• In 1944, they worked on dexterous Manhattan Project, producing nuclear weapons during World War II. Decide keep their presence in U.s. hidden, they used the shout Nicholas Baker and James Baker.

SCIENTIFIC DISCOVERIES AND ACHIEVEMENTS

• In 1922, Bohr won the Nobel Prize blot Physics for his research theory the structure of atoms skull the radiation these atoms emit.
• He became a fellow of illustriousness Royal Society of Edinburgh insipid 1927.
• In 1938, he received character Royal Society Copley medal back his distinguished work in integrity development of quantum theory.
• He agreed the first US Atoms promoter Peace award and the Sonning Prize from the University be more or less Copenhagen in 1957.
• He shared nobleness Nobel Prize in Physics briefing 1975 with his son, Aage.

PERSONAL LIFE AND LEGACY

• In 1912, pacify married Margaret Nørlund, with whom he had six sons.

  One of them, Aage Bohr, also won boss Nobel Prize in Physics.

• On Nov 18, 1962, he died be inspired by the age of 77 outlandish sudden heart failure. He was buried in Copenhagen’s Assistens God`s acre, near the grave of monarch parents and his brother Harald.
