      Lesson Summary Energy Levels in Atoms Electrons in atoms are found in fixed energy levels. Niels Bohr proposed that electrons move in specific orbits around the nucleus . In these orbits, each electron has a fixed energy called an energy level. A quantum of energy is the amount of energy needed to move an electron from one energy level to another.
