Who was Niels Bohr?

Neils Bohr was a Danish physicist, philosopher and promoter of scientific research. Bohr began research on what would become known as the Bohr model of the atom in 1911. His work was published in 1913. Bohr expanded Rutherford’s work o nuclear structure and also the quantum theory work proposed by Max Planck. He adapted them into what became widely known as the Bohr model.

    Bohr was one of the first to finalize a model that demonstrated electrons orbiting the nucleus of an atom, and also the first to theorize that an electron could move from a higher orbit to a lower one, and that in the process energy was emitted.

   Bohr explained that each element on the periodic table had chemical properties that were determined by the number and behavior of their electrons. This great scientist was awarded the Nobel Prize in Physics in 1922.
