Feb 14, 2025 · 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 was the first successful model of the atom. Developed from 1911 to 1918 by Niels Bohr and building on Ernest Rutherford's nuclear model, it supplanted the plum pudding model of J. J. Thomson only to be replaced by the quantum atomic model in the 1920s.

Feb 20, 2025 · 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.

Niels Henrik David Bohr (Danish: [ˈne̝ls ˈpoɐ̯]; 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.

Apr 24, 2023 · Bohr’s Model is an atomic model proposed by Danish Physicist Niels Bohr in 1913. According to this model, in an atom, the electrons revolve around the nucleus in definite energy levels called orbits/shells. This model provides a basic understanding of the concept of the atom and its constituents.

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....

Feb 14, 2025 · In a pivotal moment of his career, Bohr developed a revolutionary theory proposing that electrons orbit atoms in quantized energy levels, a concept that altered the understanding of atomic behavior and laid the foundation for modern quantum mechanics.

Apr 2, 2014 · Niels Bohr was a Nobel Prize-winning physicist and humanitarian whose revolutionary theories on atomic structures helped shape research worldwide.

Jan 25, 2025 · Bohr’s atomic model successfully explained the discrete spectral lines of hydrogen by proposing that electrons revolve in specific quantized orbits around the nucleus and emit or absorb energy only when transitioning between these orbits.
