The new isotope produced is ²³⁴₉₀Th (by finding
                                                                               the symbol for Z = 90 in the Periodic Table).
                                                                        b.    Beta radiation ( ⁰_ö1e emitted from nucleus):
                                                                                                         ²¹⁰₈₂Pb  =>  ⁰_ö1e  + ^A_ZX
                                                                               210= (0 + A)       A must be 210
                                                                               82 = (ö1 + Z)       Z must be 83
                                                                               The new isotope produced is  ²¹⁰₈₃Bi.
                                                                        c.    Fission (see Language of Chemistry ):
                                                                                                              ²³⁵₉₂U  +  ¹₀n  => ¹³⁹₅₆Ba  +  ⁹⁴₃₆Kr  +  3¹₀n + Energy
                                                                               235  +  1  =  139  +  94  +  3(1) (conservation of mass number)
                                                                                92  +  0  =  56  +  36  +  3(0) (conservation of charge)
                                                                               NOTE: Many other products of uranium fission in addition
                                                                               to barium and krypton are formed.
                                                                        d.    Fusion (see Language of Chemistry ):
                                                                                                  4¹₁H  => ⁴₂He  +  2⁰₁e  +  Energy
                                                                               4(1)  =  4  +  2(0)  (conservation of mass number)
                                                                               4(1)  =  2  +  2(1)  (conservation of charge)
                                                                 4.    Student Worksheet: Writing Nuclear Equations

                                                                               1.   ²³⁵₉₂U  +  ¹₀n  =>  ^A_ZX

                                                                               2.   ²²²₈₈Ra  =>   ⁴₂He  +  ^A_ZX

                                                                               3.   ^A_ZX  +  ⁰_ö1e  =>  ⁵⁴₂₄Cr

                                                                               4.   ⁵⁴₂₆Fe  +  ¹₀n  =>  ¹₁H  +  ^A_ZX

                                                                               5.   ²³⁸₉₂U  +  ¹²₆C  =>  ²⁴⁶₉₈Cf  +  4^A_ZX

                                                                               6.   ^A_ZX  +  ⁴₂He  =>  ²⁴⁵₉₇Bk  +  ¹₁H  +  2¹₀n

                                                                               7.   ²³⁵₉₂U  +  ¹₀n  =>  ¹³⁹₅₆Ba  +  ^A_ZX  +  3¹₀n

                                                                               8.   ²₁H  +  ³₁H  =>  ^A_ZX  +  ¹₀n
