The given isotope 11ea8a6b_076c_1957_a2a1_41f939ac0158_TB6108_11 represents the element radium (Ra), which has an atomic number of 88. When an alpha particle is emitted, the atomic number of the resulting atom decreases by 2. Therefore, the resulting atom would have an atomic number of 86, which corresponds to the element radon (Rn). Thus, the correct answer is B as it corresponds to the atomic number of Rn.
