Neils Bohr came up with the idea of energy levels to explain the color spectrum of hydrogen. Energy levels are like steps on a staircase. Electrons change energy levels by absorbing or emitting light. When an electron moves from a higher energy level to a lower one, the atom gives up some energy and emits it as different colors of light. The specific colors correspond to the energy between the energy levels. p. 129 Electrons and Energy Levels Electron cloud – electrons are so fast and light, that their exact position cannot be defined.
