PPT-ATOMIC SPECTRA

Objectives 1 Determine the emission spectrum of Hydrogen and other elements 2 Calculate the expected wavelengths of H using the Rydberg equation 3 Determine the composition of unknown solutions using flame tests. jdx or NIST msp format The spectra preferably should include 2 digits to the right of the decimal see Correcting for Mass SufficiencyDeficiency below The NIST program then uses two files to import the saved spectra The primary file AUTOIMPMSP is foun Largest commercial flooring contractor. in U.S..

In fact, several theoretical models of the atom have been developed over the last few hundred years. You will learn about the currently accepted model of how electrons behave in atoms.. 5. H. 5. ).
