Energy is absorbed in discrete amounts.

Calculate the wavelength of radiation absorbed during the ionization of an electron from the n = 1 energy level of hydrogen. (Hint: on the Energy Levels For Hydrogen chart, how much energy is required to ionixe an n = 1 electron?)

[removed] If the wavelength of radiation absorbed during the ionization of an electron from the n = 1 energy level of hydrogen is not within the range of visible light, within what range of electromagnetic wave does this wavelength fall?

[removed]

The Energy Levels for Hydrogen chart shows more transitions than are represented by hydrogen’s emission spectrum because hydrogen’s emission spectrum shows only[removed] lines.
