Look carefully at the picture. It shows an electron in the excited state on the left, and the electron returning to its ground state on the right. When the electron return to the ground state it emits a_______________________.
blast of cold air
electrostatic charge
proton
photon (light)
The picture shows an atom in the ground state absorbing energy and the electron jumps to the excited state. Which state has higher energy?
Ground State
Excited State
Take a close look at the picture. What is this called?
the color of life
lucky charms
spectral line
electron cloud
Line emission spectra is produced from atoms when
electrons release energy as they move to their excited state.
electrons absorb energy as they move to their excited state.
electrons release energy as they return to the ground state.
electrons absorb energy as they return to the ground state.

What evidence did you observe that proves that elements give off their own unique color spectrum?
All of the gas tubes produced a full spectrum. (A rainbow.)
When we looked at white light through a prism, we saw the rainbow.
Each gas tube gave off its own unique color and color spectrum when we looked at the light through the spectroscope. None of them were the exact same.
Each gas tube gave off the same color and color spectrum when we looked at the light through a spectroscope.
