1. Electrons can absorb energy from being heated in a flame.

2. Electrons are stable in excited states.

3. Electrons release energy as they return to the ground state.

4. The energy given off by electrons can have any value.

5. The energy of the light released is related to the difference in energy levels

6. The energy of light released is directly related to its frequency.

7. The frequency of light released is directly related to its wavelength.

Part II (not graded for correctness)

1. Suggest a reason why the heat required to vaporize 75 g of water is so much higher than the heat required to heat 75 g of water through a temperature change of 65^oC. Explain your answer.

2. Consider the following atomic notations for element A and B:

Element A: 232 Element B: 228

Th Th

90 90
