Niels Henrik David Bohr (Danish: [ˈne̝ls ˈpoɐ̯ˀ]; 7 October 1885 – 18 November 1962) was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922.
Jun 28, 2024 · Bohr model, description of the structure of atoms proposed in 1913 by the Danish physicist Niels Bohr. The Bohr model of the atom, a radical departure from earlier, classical descriptions, was the first that incorporated quantum theory and was the predecessor of wholly quantum-mechanical models.
In atomic physics, the Bohr model or Rutherford–Bohr model is an obsolete model of the atom, presented by Niels Bohr and Ernest Rutherford in 1913. It consists of a small, dense nucleus surrounded by orbiting electrons.
Bohr’s Model of an Atom. Bohr’s model consists of a small nucleus (positively charged) surrounded by negative electrons moving around the nucleus in orbits. Bohr found that an electron located away from the nucleus has more energy, and the electron which is closer to nucleus has less energy.
Aug 29, 2017 · Niels Bohr was one of the foremost scientists of modern physics, best known for his substantial contributions to quantum theory and his Nobel Prize -winning research on the structure of atoms....
Jun 2, 2024 · Niel Bohr’s Atomic Theory states that – an atom is like a planetary model where electrons were situated in discretely energized orbits. The atom would radiate a photon when an excited electron would jump down from a higher orbit to a lower orbit.
In 1913, Niels Bohr incorporated this idea into his Bohr model of the atom, in which an electron could only orbit the nucleus in particular circular orbits with fixed angular momentum and energy, its distance from the nucleus (i.e., their radii) being proportional to its energy.
Niels Bohr, Danish physicist who is generally regarded as one of the foremost physicists of the 20th century. He was the first to apply the quantum concept to the problem of atomic and molecular structure. For that work he received the Nobel Prize for Physics in 1922.
May 2, 2010 · In 1913, Niels Bohr published his atomic model, which revolutionized our understanding of the structure of the atom. This model, based on quantum theory, postulated that electrons moved in quantized orbits around the nucleus, and could only change orbit by emitting or absorbing photons of specific energy.
Aage N. Bohr (born June 19, 1922, Copenhagen, Den.—died Sept. 8, 2009, Copenhagen) was a Danish physicist who shared the 1975 Nobel Prize for Physics with Ben R. Mottelson and James Rainwater for their work in determining the asymmetrical shapes of certain atomic nuclei.
