Stable and Unstable Nuclei | Radioactivity | Physics | FuseSchool How do you know if an atom is stable? In this video we are going to learn about radioactive decay and that unstable nuclei either have too many protons or too many neutrons, which upsets the strong nuclear forces holding the atom together. Unstable nuclei try to balance themselves by giving off the excess proton or neutron either through alpha, beta minus or beta plus decay. 0:00 Introduction 0:13 Atom composition 0:45 Stable nuclei 1:06 Unstable nuclei 1:25 Radioactive decay 1:43 Alpha decay 2:11 Beta-minus decay 2:50 Beta-plus decay 3:18 Determine if the atom is stable or unstable 4:22 Summary CREDITS Design & Animation: Bing Rijper Narration: Dale Bennett Scripts: Bethan Parry SUPPORT US ON PATREON SUBSCRIBE to the FuseSchool YouTube channel for many more educational videos.
