1) how does bohr's model of the atom differ from rutherford's model? a. bohr's model states that electrons occupy orbits with fixed energy levels. b. in bohr's model, electrons occupy space within a "cloud" surrounding the nucleus. c. rutherford's model explained the physical and chemical properties of elements, whereas bohr's model only explained the physical properties. d. bohr's model proposed that electron orbitals have different shapes.
