Bohrs model was modified by

WebBohr’s model of an atom is also known as the Rutherford-Bohr Model. According to Rutherford’s model, a nucleus is positively charged and is surrounded by negatively charged electrons. Bohr modified this model by adding that the electrons travel in fixed circular orbits around the nucleus. WebBohr's model was later modified by Sommerfeld to explain some the spectral lines which Bohr's was not able to explain. Was this answer helpful? 0. 0. Similar questions. The ionization energy of the electron in the hydrogen atom in its grounds state is 13.6 eV. The atoms are excited to higher energy levels to emit radiations of 6 wavelengths.
