His many contributions to the development of atomic physics and quantum mechanics, his personal influence on many students and colleagues, and his personal integrity, especially in the face of Nazi oppression, earned him a prominent place in history.
Niels Bohr, Danish physicist, used the planetary model of the atom to explain the atomic spectrum and size of the hydrogen atom. Bohr’s theory explained the atomic spectrum of hydrogen and established new and broadly applicable principles in quantum mechanics.
From their sizes to their spectra, much was known about atoms, but little had been explained in terms of the laws of physics. For decades, many questions had been asked about atomic characteristics. In 1913, after returning to Copenhagen, he began publishing his theory of the simplest atom, hydrogen, based on the planetary model of the atom. Bohr became convinced of its validity and spent part of 1912 at Rutherford’s laboratory. The great Danish physicist Niels Bohr (1885–1962) made immediate use of Rutherford’s planetary model of the atom.
