How does the energy of an electron change when it moves from level n = 2 to n = 4?
- It increases, decreasing in magnitude by a factor of 4
- It increases, decreasing in magnitude by a factor of 2
- It decreases, increasing in magnitude by a factor of 4
- It decreases, increasing in magnitude by a factor of 2
- It decreases, decreasing in magnitude by a factor of 4.
What is the value of eV? (Note: e = 1.6 X 10⁻¹⁹ C)
- 1.6 X 10⁻¹⁹ J
- 1 J
- 1.6 X 10⁻¹⁹ C
- 1 V
- 1.6 X 10⁻¹⁹ kJ
An electron in a hydrogen atom drops from the n = 4 to the n = 1 energy level. How much energy is released?
- 12.75 eV
- 13.6 eV
- 27.2 eV
- -13.6 eV
- -12.75 eV
What does it mean to say an electron in an atom has “zero” energy?
- It is unbound (free from the nucleus).
- It is bound (orbiting).
- It is as close to the nucleus as possible.
- It would combine with the nucleus, causing radiation.
- It is completely stationary in its orbit.
