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.

In 1913, Niels Bohr, along with Ernest Rutherford, presented a model of the atom, suggesting it to be a dense nucleus surrounded by orbiting electrons. Though this "Bohr model" of the atom is now ...

Photo: Niels Bohr's research notes for his new atomic theory Rutherford's find came from a very strange experience. Everyone at that time imagined the atom as a "plum pudding." That is ...

With the help of Niels Bohr, she got a position in Stockholm. From there, Meitner and her nephew Otto Frisch proved that the uranium atom had been split. Hahn published the results in January 1939 ...

Bohr and his colleagues devised a novel way of ... which takes place when the strontium atom group becomes entangled and emits light in the field between the two mirrors. “The mirrors cause ...

SCIENCE is steadily becoming severely specialised. The proportion of amateurs (in the restricted sense of the word) among original workers of all ranks decreases slowly but surely. The average ...

Therefore, electrons cannot be arranged at random, but they must have fixed levels of energy within each type of atom. Bohr's 'solar system' model of the atom is the way that most people think ...

Atoms have a central positive nucleus. Most of the mass of an atom is found in the nucleus. 1913 Bohr In-depth work on Rutherford's model showed it had limitations. The electrons should just ...
