Chapter 6: Line Spectra and Bohr Model Flashcards
What is the continuous spectrum?
a rainbow of colors with the light of all wavelengths; no blank spots
What is the line spectrum?
emitted light from an element is passing through a prism; not a continuous spectrum

an _____ in a permitted _____ has a specific energy is in an _____ energy state
electron, orbit, allowed
energy is only _____ or ______ by an electron as it changes from one allowed _____ _____ to another
emitted, absorbed, energy state
electrons cannot stay in an _____ state forever, and when coming back to _____ state, energy is _____
excited, ground, emitted
the _____ emitted by hydrogen atom is a measure of the _____ gap between the two energy states

_____ the energy gap, _____ the wavelength
higher, lower
What is the Balmer Series?
a series of spectral emission lines of the hydrogen atom that result from electron transitions from higher levels down to the energy level with principal quantum number 2.
What are three of the emissions in the Balmer Series?
n = 3 –> 2 (red)
n = 4 –> 2 (blue)
n = 5 –> 2 (violet)
