How did the electrons keep themselves from collapsing into the nucleus, since opposite charges attract? Luckily, science was ready for the challenge! Physicists such as Niels Bohr continued to design experiments to test the nuclear model of the atom, which eventually evolved into the modern quantum mechanical model.
A Nobel Prize Winner: Neils Bohr was a Danish physicist that lived from 1885 to 1962. During his life he worked in the field of physics, winning the Nobel Prize in 1922 for his work on atomic structure. Bohr built on the ideas set forth by scientist Ernest Rutherford, who had already determined that the atom had a nucleus and subatomic particles.
The Bohr Model of the Atom. In 1913, Danish physicist Niels Bohr applied Max Planck’s quantum theory to the nuclear atom of Ernest Rutherford, thus formulating the well-known planetary model of the atom, wherein electrons orbit a central nucleus in well-defined levels of energy ( Figure 1 ). Note that Bohr stated that electrons in the atom ...
Rutherford model, description of the structure of atoms proposed (1911) by the New Zealand-born physicist Ernest Rutherford. The model described the atom as a tiny, dense, positively charged core called a nucleus, in which nearly all the mass is concentrated, around which the light, negative constituents, called electrons, circulate at some ...

What Did Niels Bohr Discover? The Niels Bohr Atomic Model theory is a model that was introduced by Niels Bohr in 1913 to describe the atom. It was a postulation of Bohr that the electrons rotated in a circular orbit around the nucleus of the atom.
Rutherford explained the nucleus of an atom and Bohr modified that model into electrons and their energy levels. 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 ...
