Question

7 the main difference between j.j. thomson and ernest rutherfords atomic models was a thomsons model positioned the protons in a dense central area while rutherfords electrons were scattered throughout the mass. b thomsons model placed the electrons in fixed orbits around the nucleus while rutherfords electrons were scattered throughout the mass. c rutherfords model positioned the protons in a dense central area while thomsons electrons were scattered throughout the mass. d rutherfords model placed the electrons in fixed orbits around the nucleus while thomsons electrons were scattered throughout the mass.

Explanation:

J.J. Thomson's plum - pudding model had electrons scattered throughout a positively - charged mass. Rutherford's model had a small, dense, positively - charged nucleus (where protons are located) with electrons in orbit around it.

Answer:

C. Rutherford's model positioned the protons in a dense central area while Thomson's electrons were scattered throughout the mass.
