WebSep 29, 2024 · The isotope symbol for iodine-131 is ""_53^131"I". The isotope symbol, called isotope notation or nuclear notation indicates both the atomic number, "Z", and the mass number, "A" of an isotope. The mass number is written as a superscript on the left-hand side of the element's chemical symbol, "X". The atomic number (no. of protons) is written as a …
WebIn alpha decay, an alpha particle is ejected from an unstable nucleus, so here's our unstable nucleus, uranium-238. An alpha particle has the same composition as a helium nucleus. … WebThe electron is bound to the nucleus by the electric force, so you get quantized energy levels related to that "system" of nucleus + electrons. But inside the nucleus, the nucleons are bound to one another by the strong nuclear force, so you also get quantized energy levels for that smaller system.
