WebNotes: Isotopes are atoms of the same element (and so with the same number of protons), but with different masses due to having different numbers of neutrons. We are assuming (and shall do all through this page) that all the ions recorded have a charge of 1+. That means that the mass/charge ratio (m/z) gives you the mass of the isotope directly. WebMode of decay: Beta particles and gamma radiation. Chemical properties: I-131 can change directly from a solid into a gas, skipping the liquid phase, in a process called sublimation. I-131 dissolves easily in water or alcohol. I-131 readily combines with other elements and does not stay in its pure form once released into the environment.
