Energy Levels!
This scientist said electrons move in fixed orbits called energy levels around the nucleus.
What is Bohr's Model?
Bohr said electrons travel in perfect circles: Win or Fail?
What is Fail?
When an electron falls back down, it releases this.
What is Light?
Electrons can have only the exact amounts of energy, no in-betweens.
What is Quantized?
The color of a light atom emits depends on this difference between energy levels.
What is Energy Difference?
When an electron absorbs energy, it does this.
What is jump to a higher energy level?
Bohr pictured electrons like planets orbiting the sun, but only allowed them in certain fixed paths.
What is Energy Levels?
Bohr explained the hydrogen spectrum perfectly: Win or Fail?
What is Win?
