Magnesium-25 is composed of 12 protons, 13 neutrons, and 12 electrons. Magnesium-26 is composed of 12 protons, 12 neutrons, and 12 electrons. WebAug 8, 2024 · A beta particle (β) is a high-speed electron emitted from the nucleus of an atom during some kinds of radioactive decay (see Figure 11.4.2 ). The symbol for a beta particle in an equation is either β or e − 0 1. Carbon-14 undergoes beta decay, transmutating into a nitrogen-14 nucleus. C14 6 → N14 7 + e − 0 1.
