While researching a topic, a student has taken the following notes:
- When the electrons of a chemical element change energy states, certain wavelengths of light are released.
- This unique collection of wavelengths is known as the emission spectrum of the element.
- Magnesium’s emission spectrum includes the 517.2 nanometer (nm) wavelength.
- Helium’s emission spectrum includes the 587.5 nm wavelength.
- The green portion of the visible spectrum is made up of light with wavelengths of 500–570 nm.
The student wants to identify an emission spectrum that includes a wavelength in the green portion of the visible spectrum. Which choice most effectively uses relevant information from the notes to accomplish this goal?
Containing the 517.2 nm and 587.5 nm wavelengths, respectively, both magnesium’s and helium’s emission spectra include wavelengths in the green portion of the visible spectrum.
A
Magnesium’s emission spectrum includes the 517.2 nm wavelength, which is in the green portion of the visible spectrum.
B
The 587.5 nm wavelength, which is in the green portion of the visible spectrum, is one wavelength in the emission spectrum of helium.
C
Since the 517.2 nm wavelength of light is within the 500–570 nm range, it is part of the green portion of the visible spectrum.
D
