The AP Chemistry Exam is designed so that it is impossible to know absolutely everything on it (in case you haven’t noticed). I might as well place the biggest two at the start – You need to review your incorrect MC from the Pra ...

Rutherford backscattering spectrometry
Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science. Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.
