States and lower states, including the ground state. Lines show the energy differences between different excited You will look at these lines in this lab. Produce very sharp lines in a spectrum when they are Ordinary CD is a reflective diffraction grating. To create a visual spectrum in a way that places the Spectroscope is a device which uses a diffraction grating Spectroscope, a prism, or a diffraction grating. A spectrum is the scientific name forĪ rainbow: light broken into the different wavelengths Gives rise to a way to uniquely identify elements based State and the higher energy levels is different. The photons emitted precisely match the quantumĮnergy difference between the excited state and theįor different elements the spacing between the ground Proportional to the frequency of the light (remember: E = When anĮlectron is in a higher-energy shell it is said to be inĮlectrons in excited states do not usually stay in themįor very long. Promotes them to the higher-energy shell. With electricity their electrons can gain energy. Second, when atoms are heated or energized Right amount of energy to move it from one quantum shell First, the electron can absorb a photon of just the Possible energy level they are said to be in the When all of the electrons are at the lowest The electrons in an atom occupy different energy levels,Īs you know. They will record the spectra they observe. Students will closely observe the spectrum of light produced by atomic emission gas discharge tubes using simple spectroscopes. Levels, atomic emission spectroscopy, and the spectral In this lab students will learn about atomic energy
