Fill in the blank. The higher the energy the _________ the wavelength.
slower
longer
faster
shorter
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)
Violet. This light has the shortest wavelength.
Red. This light has the shortest wavelength.
Red. This light has the longest wavelength.
Violet. This light has the longest wavelength.
Does a gas discharge tube filled with boron emit the same wavelengths of light as a tube filled with hydrogen? Why / why not?
Yes. Since both boron and hydrogen emit the same colors, they are emitting waves of the same wavelength.
No. Even though both gases emit violet, blue-green, and red, the colors of light are different wavelengths.
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.
The electron is releasing energy
The electron is moving to a lower energy level.
The electron is gaining energy
The electron is moving to a higher energy level
Which image in model 3 has the electron transition n = 5 to n = 2?
A
B
C
D
This electron (from question 16) moves from a ________ energy state to a ________ energy state.
higher, higher
lower, lower
lower, higher
higher, lower
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
Use the information from hydrogen emission spectrum in Model 2 to match each image with the correct color of light that is being emitted.
