Nuclear Decay Modes on a Graph [Half-life, video 02]

Video 2 of the Half-Life series of short animations about nuclear physics. Shows the position of a range of unstable nuclides on a proton number v. neutron number graph. Stable nuclides are shown for reference. Unstable nuclides that decay by alpha, beta plus, beta minus and spontaneously fissile nuclides are shown.
Relevant concepts: alpha particles, beta particles, gamma photons, electron neutrinos, electrons, positrons, weak interaction, metastable nuclei, alpha decay, beta decay, gamma decay, neutron decay, spontaneous fission, radioactive transformations, nuclear decay, proton number and nucleon number.
