The light emitted from a flame

SpletScience Chemistry Potassium atoms in a flame emit light as they undergo transitions from one energy level to another that is 4.9 × 10-19 J lower in energy. Calculate the wavelength of light emitted and, by referring to Figure 4.3, predict the colorvisible in the flame. Splet22. maj 2024 · The colors observed during the flame test result from the excitement of the electrons caused by the increased temperature. The electrons “jump” from their ground state to a higher energy level. The color emitted by larger atoms is lower in energy than the light emitted by smaller atoms. Why do some elements give flame a distinct Colour?
