need answers for all 4:) please answer them i really need help!

Alpha decay daughter product is 230Th. What was the original radioisotope that decayed? original isotope (mass\#.atomic\#,element symbol): Beta decay dajghter product is helium-3. What was the original radioisotope that decayed? original isotope (mass\#, atomic\#,element symbol): In a fission reaction, barium-141 and a second daughter product atom plus some extra neutrons are produced by the bombardment of a Uranium-235 dtom with a neutron. What is the missing daughter product? (hint: there are three neutrons, be sure you add the mass of the neutron in three times). 92235U+01n56141Ba+??+301n second daughter product (mass\#t, atomic\#,element symbol): A theoretical fusion reaction equation could be 11H+13H ?? What would be the fusion product? fusion product (mass\#,atomic\#,element symbol)
