- Elements that appear in the same column of the periodic table often share similar chemical properties. For alkaline earth metals, this is troublesome because the body treats radium (a radioactive element) like calcium, storing it in the bone marrow. The radium then bombards nearby bone cells with alpha particles, causing them to "crumble." Radium poisoning investigations often center on the identification of radium and its isotopes in bone samples using a mass spectrometer. Pictured is a schematic of a simplified mass spectrometer that shows the paths of calcium isotopes, barium (another alkaline earth metal) isotopes, and radium isotopes entering the chamber. +++++++++ lonized Detector B C D E F G Using the data shown in the table, calculate the path radius r of the Ca ion.
