Name: ____________________________________ Period:_________ Page # _____ Emission Spectra and Energy Levels Worksheet Discusion:One convenient method of exciting atoms of an element is to pass an electric current through a sample of the element in the vapor phase. This is the principle behind the spectrum tubes in the demonstration. PPTX Ch5 Modern Atomic Theory - Henry County Schools / Overview The three groups of lines in the hydrogen spectrum correspond to the transition of electrons from higher energy levels to lower energy levels. The Lyman series corresponds to the transition to the n 1 energy level. The Balmer series corresponds to the transition to the n 2 energy level. The Paschen series corresponds to the transition to the n Analyzing Spectra - physics.weber.edu Analyzing Spectra Worksheet. Part 1: Pre-exercise Exercise.

EmissionSpectraEnergyLevelsPractice.pdf - Name Date Pd Emission Spectra ... When visible light energy from a spectrum tube is passed through a diffraction grating, a bright line spectrum, or line-emission spectrum is produced. Each element has its own unique emission spectrum by which it can be identified, analogous to a fingerprint. Such a spectrum consists of a series of bright lines of definite wavelength. Each wavelength can be mathematically related to a definite quantity of energy produced by the PDF Atomic Emission Spectra - Winston-Salem/Forsyth County Schools ery element has a unique atomic emission spectrum, as shown by the examples of mercury (Hg) and strontium (Sr). Classical theory was unable to explain the existence of atomic emission spectra, also known as line-emission spectra. According to classical physics, a ground state atom would be able to absorb any amount of energy rather than only 2

Consider the energy level diagram of the hydrogen atom according to the Bohr model (right). (a) Is a photon of light absorbed or emitted when an electron goes from the level n = 4 to n = 3? Give your reasoning. (b) What is the energy of a photon, in J, that is emitted or absorbed when Student Worksheet: Graphing Spectra - NASA We can identify three bright lines for hydrogen in the top spectrum. Measuring from the scale, the wavelengths are 435 nm (purple), 486 nm (blue) and 657 nm (red). Recall (e.g. from the Calculation Investigation) that the the frequency is given by n = c / l, and the energy is given by E = h n (where h = 6.626 x 10-34 J-s, and c = 3 x 10 8 m/s). In the table below we summarize the frequency and energy results for these lines.
