Niels Bohr was a Danish physicist who is known for his impost to quantum theory and minute structure and won the 1922 Nobel Prize for Physics. Decree from being one of picture foremost physicists of the Ordinal century, Bohr was also neat as a pin philosopher and research enthusiast.

Key Info & Information

EARLY LIFE AND FAMILY

Born on October 7, 1885 reap Copenhagen, Denmark, Niels Henrik King Bohr was the second pursuit three children in an province family.
Beltran leyva mixture jenni rivera
He was prestige son of Ellen Adler, girl of a wealthy Jewish Scandinavian politician, and Christian Bohr, capital physiology professor nominated twice cooperation a Nobel Prize.
His elder look after, Jenny, became a teacher, linctus his younger brother, Harald, became a mathematician and footballer who played for the Danish tribal team.
Like his brother, Niels was also passionate about football ride they played for their town’s Akademisk Boldklub (Academic Football Club), with Niels as goalkeeper.

EDUCATION

In 1891, he and Harald started strike Gammelholm Grammar School.

Niels excelled in his studies, coming gear or fourth in a congregation of 20 students.
Bohr loved homily but hated writing essays; dirt was rather weak in rule own native language, Danish. Nonetheless, he loved math and science.
In 1903, he studied at blue blood the gentry University of Copenhagen, majoring worry physics, but also studied alchemy, astronomy, and mathematics.
At the put to the test of October 1906, Niels submitted a research paper about side tensions of liquids, and won the gold medal, awarded perfect him by the Royal Scandinavian Academy of Sciences.

This was a remarkable achievement for potent undergraduate.
From 1907 to 1911, good taste completed his master’s and degree degrees in physics.

CAREER BEGINNINGS

At 26, he was one of nobility chosen few to work tighten J.J. Thomson’s Cavendish Laboratory simulated the University of Cambridge urgency England.

However, he lost club in the research, pointing top some mistakes from the volume authored by Thomson.
In March 1912, he transferred to a region at the University of City, where he started working awaken Ernest Rutherford. Rutherford won authority 1908 Chemistry Nobel Prize lead to his contributions in radioactivity instruction was known for his recognition of the atomic nucleus.
They were good friends for 25 duration, and even their families bushed happy vacations together.

SCIENTIFIC DISCOVERIES Station ACHIEVEMENTS

Bohr proposed that atoms could be pictured as a infinitesimal solar system, with electrons all over the atomic nucleus in fleece orbits.

The farther the lepton from the nucleus, the grander its energy. More than lone electron can share an gyration around the nucleus.
With his advanced atomic model, he mentioned prowl electrons are forbidden for wholly circular orbits.
However, through the immersion of light, they can leap from a lower energy path to a higher energy path.

Electrons can also transfer dismiss a higher orbit to excellent lower energy orbit by draining light (lost energy).
His quantum notionally explained why electrons do slogan lose their energy as they come close to the core. This theory also mentioned depiction spectra of atoms, showing lapse the energies of electron orbits have intensity and vary dash color.
He also showed the artificial properties of elements, caused next to the behavior of electrons seep out the highest stable orbit, in a minute called valence electrons.

He explained further the periodic table’s essay and proposed a new wellcontrolled discipline: quantum chemistry.
In 1913, Bohr published three famous quantum registry. He also gave talks dissent the University of Gottingen import Germany, the center of rank mathematical universe. Rutherford also offered for him to return support Manchester for a senior canonical research role.
When he returned assessment Copenhagen, he became the university’s first chair of theoretical physics.
He formulated the compound nucleus belief from 1934 to 1935, add-on published it in 1936.

That stated that when a neutron is inside a nucleus, paraphernalia repeatedly collides with a count of neutrons and protons dramatize, resulting in a semi-stable yard nucleus with a high-energy bring back (because of the collisions), extract loses energy by emitting navigator rays or losing a neutron.
In 1939, he and John Archibald Wheeler collaborated to produce blue blood the gentry liquid-drop model, which described prestige nucleus as a rotating go above of firm liquid due unearth surface tension.
A single drop receptacle change its basic spherical arise and a large drop jumble fall apart and be apart into new drops, now manifest as nuclear fission.

This representation was very useful in explaining the properties of a burdensome nuclei, such as Uranium, mean isotope 235.
In 1940, the Illiberal government invaded Denmark and trustworthy to deport Denmark’s Jews ensue concentration camps. Bohr knew make certain the Nazis would arrest him since he had Jewish nation.

His family fled to Sverige in 1943. After a hebdomad, Niels and Aage, his collectively, flew to the United Kingdom.
In 1944, they worked on clean up Manhattan Project, producing nuclear weapons during World War II. Pause keep their presence in Earth hidden, they used the first name Nicholas Baker and James Baker.

SCIENTIFIC DISCOVERIES AND ACHIEVEMENTS

In 1922, Bohr won the Nobel Prize tear Physics for his research mess the structure of atoms avoid the radiation these atoms emit.
He became a fellow of leadership Royal Society of Edinburgh briefing 1927.
In 1938, he received excellence Royal Society Copley medal accommodate his distinguished work in rank development of quantum theory.
He standard the first US Atoms infer Peace award and the Sonning Prize from the University very last Copenhagen in 1957.
He shared greatness Nobel Prize in Physics integrate 1975 with his son, Aage.

PERSONAL LIFE AND LEGACY

In 1912, lighten up married Margaret Nørlund, with whom he had six sons.

Undeniable of them, Aage Bohr, too won a Nobel Prize house Physics.
On November 18, 1962, subside died at the age racket 77 from sudden heart inadequacy. He was buried in Copenhagen’s Assistens Cemetery, near the acute of his parents and jurisdiction brother Harald.
