How do isotopes decay

WebAtomic nuclei consist of protons and neutrons bound together in tiny bundles at the center of atoms. Radioactive nuclei are nuclei that are unstable and that decay by emitting energetic particles such as photons, electrons, neutrinos, protons, neutrons, or alphas (two protons and two neutrons bound together). 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. We saw the helium nucleus in the previous video. There are two protons in the helium nucleus and two neutrons.
