    FLAME TEST Summary The purpose of this lab was to see how different compounds can change color while in a flame and with this color‚ I can identify the compound. The test involve putting sample element and see what color appears. Also Thermal excited electron goes from low to high energy level which raises the color but when the excitation ends electron gets to lower level which makes the color back to normal. In order to determine the identity of several unknowns‚ I will perform flame tests and

    Boake‚ Hannah Harper Various Color of Light as the Effect of Electron Emission Objective Observe the characteristic colors produced by certain metallic ions when vaporized in a flame. Identify the unknown metallic ions by means of its flame tests. Background When atoms absorb energy‚ electrons move into higher energy levels‚ and these electrons lose energy by emitting light when they return to lower energy levels. Energy levels are fixed energies that electrons can have. Ordinary light
