Quizplus · Accepted Answer

Starting with the given isotope, 11eb6911_399c_58b2_bb3a_471875e261e2_TB8309_11, two alpha emissions will convert it to radium-226 (by subtracting 4 from the atomic number and 8 from the mass number). 
Radium-226 will undergo two beta emissions, resulting in the addition of two protons to the nucleus (by adding two to the atomic number) and two neutrons (by adding two to the mass number), resulting in thorium-230.
