Alpha Decay of Uranium-235: Nuclear Reaction Diagram Explained #3893039 (License: Personal Use)

The image depicts the alpha decay process of uranium-235 (²³⁵₉₂U), where the unstable parent nucleus ejects an alpha particle-composed of two protons and two neutrons (⁴₂He)-to form a more stable thorium-231 (²³¹₉₀Th) daughter nucleus. Each sphere represents nucleons: green for neutrons, orange for protons. The reaction conserves both mass number (235 = 231 + 4) and atomic number (92 = 90 + 2).

Used in educational materials on nuclear physics, radioactive decay, and nuclear chemistry-especially in high school or undergraduate curricula. Matches user intent for visual learning, exam preparation, or conceptual clarification of alpha decay mechanisms.
