oppositely charged objects attract each other. this attraction holds electrons in atoms and holds atoms to one another in many compounds. however, ernest rutherfords model of the atom failed to explain why electrons were not pulled into the atomic nucleus by this attraction.\nwhat change to the atomic model helped solve the problem seen in rutherfords model?\n- bohrs work with atomic spectra led him to say that the electrons were limited to existing in certain energy levels, like standing on the rungs of a ladder.\n- bohrs work with cathode rays led him to say that the electrons were located within the mass of positive material, like plums in a pudding.\n- thomsons work with cathode rays led him to say that the electrons were located within the mass of positive material, like plums in a pudding.\n- thomsons work with atomic spectra led him to say that the electrons were limited to existing in certain energy levels, like standing on the rungs of a ladder.

Answer

Brief Explanations:

Bohr's atomic model proposed electrons exist in discrete energy levels. This addressed the issue of electrons not being pulled into the nucleus in Rutherford's model. Thomson's plum - pudding model is different and not related to solving Rutherford's model problem. Also, Thomson worked on cathode - rays for his model and Bohr worked on atomic spectra for his.

Answer:

A. Bohr's work with atomic spectra led him to say that the electrons were limited to existing in certain energy levels, like standing on the rungs of a ladder.
