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. Beta- particles (electrons) have mass number of 0 and atomic number of -1. Th is atomic number 90, so: Final mass number = 232 - 6*4 - 4*0 = 208.
Thorium is generally a health hazard only if it is taken into the body. External gamma exposure is not a major concern because thorium emits only a small amount of gamma radiation. Although thorium-229 has a much higher gamma component than either thorium-232 or thorium-230, thorium-229 comprises a very small fraction of natural thorium. element that has an atomic number of 90 and a mass number of 232,0381 in the period 7 actanide series periodic table.
238 decays form fissile U and Pu, respectively. where E' is the neutron energy after collision with a moderator atom of mass number A. From n fuel material (natural uranium and natural thorium, Fig. III, for the transport of radioactive material, means a number which is used to the parent nuclide is Th-232, in the case of U-natural the parent nuclide is U-238.
The atomic mass of thorium is 232 and its atomic number is 90 . During the course of its radioactive disintegration 6alpha and 4beta - particles are emitted.
