Bohr tried to explain the connection between the distance of the electron from the nucleus, the electron's energy and the light absorbed by the hydrogen atom, using one great novelty of physics of ...

Bohr’s atomic orbits . S. Egts. In Bohr’s model of the hydrogen atom, one electron, carrying a negative electrical charge, circles a nucleus consisting of a single proton, which has a positive ...

Niels Bohr's model of the hydrogen atom—first published 100 years ago and commemorated in a special issue of Nature—is simple, elegant, revolutionary, and wrong. Well, "wrong" isn't exactly ...

The radiation emerging from the atom as the electrons settle into stable orbits can tell us a lot about the nucleus. Shortly after Bohr's discovery, Henry Moseley discovered that energetic photons ...

Niels Bohr won a Nobel Prize for the idea that an atom is a small, positively charged nucleus surrounded by orbiting electrons. He also contributed to quantum theory.

Bohr began to work on the problem of the atom's structure. Ernest Rutherford had recently suggested the atom had a miniature, dense nucleus surrounded by a cloud of nearly weightless electrons.

Rutherford and Bohr describe atomic structure 1913. ... For one thing, the orbiting electrons should give off energy and eventually spiral down into the nucleus, making the atom collapse.

The quantum fix. Famed Danish physicist Niels Bohr was the first person to propose a solution to this issue. In 1913, he suggested that electrons in an atom couldn't just have any orbit they wanted.

It still shares some similar concepts with the Bohr model. For instance, if an atom heats up (i.e., is energized), ... the electrons don’t really “move” around the nucleus in orbits.

Some atomic nuclei are not shaped like rugby balls, as a longstanding theory suggests, but are instead somewhat flattened, ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic ...

By the laws of physics, the orbiting electrons should eventually crash into the nucleus and destabilize the atom. Bohr eventually tweaked Rutherford’s model by explaining that the electrons ...
