Early Life:

Niels Henrik David Bohr was born in Copenhagen, Denmark on October 7, 1885 and died in Copenhagen on November 18, 1962. Son of Christian Bohr, Professor of Physiology at Copenhagen University, Niels, together with his younger brother Harald, grew up in an atmosphere most favorable to the development of his genius. His father was an eminent physiologist and was largely responsible for awakening his interest in physics while still at school, his mother came from a family distinguished in the field of education.


Bohr went to Copenhagen University and took his Master's degree in Physics in 1909 and his Doctor's degree in 1911. Later, he made a stay at Cambridge University, where he profited by following the experimental work going on in the Cavendish Laboratory under Sir J.J. Thompson guidance.

Physics Studies and Atomic Model:

In 1913, he passed on to a study of the structure of atoms on the basis of Rutherford's discovery of the atomic nucleus, and since 1920 (until his death in 1962) he was at the head of the Institute for Theoretical Physics, established for him at that university.

During his work on the atomic structure, he succeeded in working out and presenting a picture of atomic structure that, with later improvements, still serves as clarification on the physical and chemical properties of the elements.

Here are some pictures and videos that both exemplify and model Niel Bohr's theory on the atom.

This model of Bohr’s idea of the atomic structure shows how it works. The nucleus lies in the center of the model and is made up of a certain number of protons and neutrons. Each of the outer layers is made up of a certain amount of electrons. The limit to how many electrons can be in each electron shell is shown in the model. This model helps not only with the theoretical appearance of an atom, but also how different elements combine.

This model of Bohr’s idea of atomic structure shows the model when it is representing a certain element such as helium in this picture. There are two protons and two neutrons in the nucleus an there are two electrons that fit on the first electron shell.

This video summarizes Bohr's model of the atom and even gets into technical details that weren't outlined in this wiki.
