Le thorium (Th) comme tous les éléments de numéro atomique supérieur à celui du plomb, ne possède aucun isotope stable. Cependant, il possède six isotopes présents dans la nature et l'un d'eux, le thorium 232 (232Th), est relative The element numbers range from 90 to 96 - Thorium (no. Beginning with naturally occurring thorium-232, this series includes the following elements: The details in decay chain (symbol, atomic mass, number of protons, half-life, de 17 Sep 2007 Thorium-232 with an atomic mass number of. 232 eventually decays to lead-208 with an atomic mass number of 208. 6. Nuclear Energy Agency/ Thorium-232 can be converted into thorium-233 by bombardment with making a critical mass of uranium in which a runaway chain reaction could occur. first of the transuranium elements, which have higher atomic numbers than uranium.

During the course of its radioactive disintegration `6 alpha` and `4 beta` particles are emitted. What is the atomic mass and atomic number of the atom? Thorium has a mass number of 232 and atomic number of 90. If it undergoes alpha particle emission, the resulting nuclei will be Answer: Radium with mass number-228 and atomic number-88. 2014-12-04 · 208Pb (mass number 208, atomic number 82) Alpha particles have mass number 4 and atomic number of 2.
