The given isotope, 11ea8a6b_bbed_d15c_9ee3_b94d052736c6_TB6109_11, can be identified as the alpha decay product of thorium-232 (232Th). The alpha particle consists of two protons and two neutrons, which means that the atomic number of the resulting atom decreases by 2. Therefore, the resulting atom has an atomic number of 90 (which is the atomic number of thorium minus 2) and is the element radium (Ra), a common alpha-emitting radioisotope.
