Excited vs Ground Electron Configurations

The Science of Fireworks Have you ever wondered what gives fireworks different colors? The color of a firework relates to the atoms that compose the firework and their electrons. Watch the video to learn about how electrons can move around in the atom to create the colorful fireworks we see on the 4th of July. Model 1: Excited versus Ground State Electron Configurations In class we have learned to represent electrons in an atom using electron configurations and Bohr configurations. The electron configurations we have been writing represent electrons in the ground state, or electrons in their lowest energy levels. According to Bohr electrons are able to jump from principal energy levels in the atom. When an electron gains energy it adopts an excited state configuration. In the excited state all of the electrons are not in the lowest possible energy level. Examine the table below to compare and contrast excited versus ground state configurations. Use the video and reading above to answer the questions below. 1. How many electrons are found in each of the following atoms ground state configuration?Carbon = 6 Oxygen = 8 Lithium = 3 Sodium = 112. How many electrons are found in each of the following atoms excited state configuration?Carbon = 6 Oxygen = 8 Lithium =3 Sodium = 113. Does the number of electrons change for an atom when it goes from ground to excited? No 4. How do the configurations differ from the ground state to the excited state? 5. Which definition that best fits a ground state electron configuration? Electrons are in their lowest possible energy levels. Electrons are not in their lowest possible energy levels. 6. Which definition that best fits an excited state electron configuration? Electrons are in their lowest possible energy levels. Electrons are not in their lowest possible energy levels Use your definitions of excited and ground state electron configurations to classify each of the following electron configurations as excited or ground.
