Chemistry 2500- Exercise C4 The Emission Spectrum of Atomic Hydrogen Objective The purpose of this lab was to calculate an experimental value for the Rydberg constant and then the ionization energy for the hydrogen atom. These values will be obtained by using a prism spectrograph to measure the wavelength value for a section of the visible line spectrum of atomic hydrogen. Theoretical Background When H+ combines with an electron it forms it’s excited state‚ H. This excited atom

Introduction Atomic Absorption Spectrometer (AAS) is an analytical equipment commonly used for the detection of heavy metals in particular sample. The first step to analysis in the AAS is the atomization of the desired element by converting it to a gaseous state. The atoms then absorb the energy emitted from the hollow cathode lamp corresponding to the desired element and a detector reads the signal and records the results. The results may be used quantitatively or qualitatively depending on the
