Web27 de abr. de 2014 · Rutherford proposed that the atom is mostly empty space. The electrons revolve in circular orbits about a massive positive charge at the centre. His model explained why most of the α particles passed straight through the foil. The small positive nucleus would deflect the few particles that came close. WebRutherford's model of an atom was modified because it did not accurately. explain the structure and behavior of atoms. Bohr's model added the idea of electrons orbiting the nucleus in fixed energy levels and provided a better explanation of the structure and behavior of atoms. 18. he modified rutherford's atomic model Answer: To remedy the ...
