Everything You'll Have Covered

What were the positives and negatives of Rutherford's atomic model?

~ Rutherford's model helped identify the basic structure of atoms because it revealed new information about the relationship between an atom's nucleus and its electrons. His model did not correctly explain the movement of electrons in an atom, however.

What was incorrect about Rutherford's atomic model?

~ Rutherford's model indicated that an electron travels in a spiral toward the nucleus and performs electromagnetic radiation until it stops moving. This idea indicated that an atom is continuously unstable.

How does Bohr's atomic model differ from Rutherford's?

~ Bohr's model states that electrons orbit around an atom's nucleus. Bohr also stated that electrons may be transferred to a different orbit by either absorbing or emitting energy through radiation. This idea is in direct contrast to Rutherford's model, which stated that electromagnetic radiation will eventually stop as the electron makes its way toward the nucleus.

How does Bohr's atomic model explain the discrete spectrum of hydrogen?

~ Bohr concluded that electrons move in orbits that have a constant energy level. Electrons can move to a higher or lower energy level based on the amount of electromagnetic energy absorbed or emitted by the electron. This amount of energy corresponds to the difference in energy between the orbits. Because the energy differences are constant, only certain frequencies of electromagnetic radiation can be emitted.
