Stability of Atomic Nuclei
• Only 2 stable isotopes (H, He) have more p than n• Up to Ca, stable isotopes may have equal numbers
of p and n or one or two more n than p• Beyond Ca, stable isotopes must have a ratio of
n:p that is greater than one• Beyond Bi, (83p, 126n) there are no stable
isotopes, heavier nuclei cannot be held together• Elements with even atomic numbers have more
stable isotopes than those with odd atomic numbers
![Page 46: Show the Arrangement of Particles in Solid, Liquid and Gaseous Water SolidLiquid Gas](https://reader036.vdocuments.mx/reader036/viewer/2022062421/56649d145503460f949e95a5/html5/thumbnails/46.jpg)
What Holds a Nucleus Together?• The mass of 1 p = 1.0073 amu and the mass of 1 n
= 1.0087 amu. Therefore an alpha particle (2p, 2n) has an expected mass of 4.0320 amu.
• The actual mass of an alpha particle = 4.0015 amu. The difference, 0.0305 amu, is called nuclear mass defect.
• Mass defect can be converted into energy units using E=mc2
• This amount of energy is released when the nucleus is formed and is called nuclear binding energy.
