In the case of thorium (A = 232 and Z = 90), we obtain an isotope of lead (A = 208 and Z = 82) after some radioactive disintegrations. The number of alpha and beta particles emitted are, respectively, In the case of thorium (A = 232 and Z = 90) respectively we obtain an isotope of lead (A = 208 and Z = 82) after some radioactive disintegrations.
