Key points. 1  Bohr's model of hydrogen is based on the nonclassical assumption that electrons travel in specific shells, or orbits, around the nucleus. 2  Bohr's model calculated the following energies for an electron in the shell, nnnn:
Under Rutherford's tutelage, Bohr began studying the properties of atoms. Combining Rutherford's description of the nucleus and Planck's theory about quanta, Bohr explained what happens inside an atom and developed a picture of atomic structure. This work earned him a Nobel Prize of his own in 1922.nder Rutherford's tutelage, Bohr began studying the properties of atoms.
