X-Ray Fluorescence (XRF) spectrometry for materials analysis and discovering "the atomic number" Documents
Aleena Tasneem Khan, and
Muhammad Sabieh Anwar
In this experiment students use XRF spectroscopy to analyze a sample's elemental composition. From the characteristic X-ray energies, Moseley's Law, a proof of the existence of the atomic number, is verified. The atomic number increases in regular steps with an increase in the characteristic X-ray energy. We will use this relationship to find the Rydberg's energy constant and screening coefficient for K X-rays.
