If U-238 splits into two even pieces, and each piece emits an alpha particle, what elements are produced?

alpha particle = 2 protons , 2 neutrons
U238 has
92 protons
146 neutrons
divide in half
46 protons
73 neutrons
subtract 2 of each
44 protons = Ru = Ruthenium
71 neutrons, unlikely isotope of Ru, which generally would have about 57 neutrons
