Questions and Answers
According to Bohr's model, how do electrons maintain their energy while in an orbit?
According to Bohr's model, how do electrons maintain their energy while in an orbit?
- They absorb energy continuously as they revolve.
- They neither gain nor lose energy in stable orbits. (correct)
- They gain energy from the nucleus.
- They lose energy and change orbits.
What does Bohr's second postulate state about an electron in a stable orbit?
What does Bohr's second postulate state about an electron in a stable orbit?
- It emits light in a continuous spectrum.
- It can easily jump to a lower energy level.
- It does not gain or lose energy. (correct)
- It radiates energy continuously.
What flaw did Rutherford's atomic model have regarding the behavior of electrons?
What flaw did Rutherford's atomic model have regarding the behavior of electrons?
- Electrons were stationary and did not revolve.
- Electrons emitted constant energy as they revolved.
- Electrons would spiral inward and collapse to the nucleus. (correct)
- Electrons had varying orbits that constantly changed.

Study Notes
Rutherford's Atomic Model Limitations
- Rutherford's model, with electrons orbiting a positive nucleus, failed to explain why electrons didn't lose energy and spiral into the nucleus.
- The model also couldn't explain the observed discrete (line) spectra of light, which contradicted the prediction of a continuous spectrum.
Bohr's Atomic Model
- Postulate 1: Electrons revolve around the nucleus in specific circular paths called orbits, each having a fixed energy level.
- Postulate 2: Electrons in these stable orbits neither emit nor absorb energy.
- Postulate 3: The further an electron's orbit is from the nucleus, the higher its energy level.
