Question

what did bohrs model of the atom include that rutherfords model did not have? a nucleus energy levels electron clouds smaller particles

Explanation:

Rutherford's model described the atom as having a dense nucleus with electrons orbiting around it but did not specify distinct energy levels for the electrons. Bohr's model added the concept of electrons existing in specific, quantized energy levels around the nucleus. A nucleus was in Rutherford's model. Electron clouds are part of the quantum - mechanical model (not Bohr's). Smaller particles (like protons, neutrons which are part of the nucleus concept) were also part of Rutherford's understanding in a general sense (as he knew about the nucleus which contains protons, and later neutrons were discovered).

Answer:

energy levels
