1. Record the colors observed in the alkali metal flame tests: Lithium: Sodium: Potassium: The emissions in these flame tests are produced when the valence electron in gas phase Group IA atoms falls from a higher energy orbital to a lower energy orbital. Demonstrate your understanding of this process by using three arrows to represent the three electrons in an atom of lithium and show how one of the valence electron "falls" from a higher-energy orbital in the excited-state configuration to a lower energy orbital in the ground-state configuration. 2p 2p 2s 2s 1s 1s Li Excited-State Li Ground-State 2. Visible light can be sorted by color (wavelength and frequency) from lower energy to higher energy: Red orange yellow green blue violet Higher Energy Lower Energy Given the color of light emitted when the electron drops from the higher-energy orbital to the lower-energy orbital, which energy gap do you predict to be larger? Which gap represents a greater energy change for the electron transition? 2p-2s gap in Li 3p-3s gap in Na or
