• B. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> protons
• C. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> nucleus
• D. <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> atoms

Answer 1

The correct option is C <!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> nucleus

In modification of Bohr's model, Sommerfeld retains the first of Bohr's orbit and adds an elliptical orbit to his second orbit. Then two elliptical orbits were added to Bohr's third orbit and so on. These changes were made such that, the nucleus of the atom was at one of the principle foci of these elliptical orbits.
