Electron Energy and Light 

Use Model 1 to answer questions 2-9.

1

Do all colors of light travel at the same speed?

1

Do all colors of light have the same energy?

1

Even though all colors of light travel at the same speed, they all have different amounts of energy. Which color has the lowest energy of light?

1

Even though all colors of light travel at the same speed, they all have different amounts of energy. Which color has the highest energy of light?

1

Light travels in a wave. Which color corresponds to the longest wavelengths?

1

Which color corresponds to the shortest wavelengths?

1

Fill in the blank. The higher the energy the _________ the wavelength.

Use Model 2 to answer questions 10 - 14. 

1

Which of the colors seen in the emission spectrum for both boron and hydrogen is highest in energy? Why? (hint: you may need to refer back to the beginning of this activity)

1

Does a gas discharge tube filled with boron emit the same wavelengths of light as a tube filled with hydrogen? Why / why not?

1

The arrow in the diagram below displays the movement of an electron in an atom. Select the best descriptions of what is happening to the electron.

Use Model 3 to answer questions 16-19.  

1

Which image in model 3 has the electron transition n = 5 to n = 2?

1

This electron (from question 16) moves from a energy state to a energy state.

1

Match each image with the correct electron transition.

n = 6 to n = 2
n = 5 to n = 2
n = 4 to n = 2
n = 3 to n = 2
n = 2 to n = 6
n = 2 to n = 4
n = 2 to n = 3

1

Use the information from hydrogen emission spectrum in Model 2 to match each image with the correct color of light that is being emitted.

violet
blue-violet
blue-green
red
