Using the golf ball analogy, where the golf ball represents the nucleus of a hydrogen atom, what would be the ratio of the diameter of the nucleus to that of the complete atom? 1. 2. What was the key piece of evidence used by Rutherford to claim that an atom was mostly empty space? 3. Which wavelength is the most energetic? Which is the least energetic? 4.

Question
I already have my answers for some of them, but just wanted to double check...specially the last 4 questions...
Using the golf ball analogy, where the golf ball represents the nucleus of a hydrogen atom, what
would be the ratio of the diameter of the nucleus to that of the complete atom?
1.
2.
What was the key piece of evidence used by Rutherford to claim that an aton was mostly empty
space?
Which wavelength is the most energetic? Which is the least energetic?
3.
4.
What do you notice about the colour of the light produced from the hydrogen tube?
5.
If the tube produced all frequencies of visible light, what colour would the light be?
6.
The scale is in nanometers (nm). How many nanometers in a meter?
7.
Record (in chart form) the wavelength of each of the coloured lines in the hydrogen emission
spectrum
8.
Which gas most closely matches the emission spectrum? Explain how you came to this conclusion.
9.
What is the relationship between the number of levels and the number of lines?
If an atom had 7 energy levels (n =1 to n = 7) how many spectral lines would we expect to be able to
see? How many of these lines would be in the visible region?
10.
