The following are artificial nuclear reactions that occur by bombardment. Balance each equation, identifying the missing particles' mass number, atomic number, and element symbol:
238/92 U + 14/7 N ---> _ + 5 1/0 n
252/98 Cf + _ ---> 257/103 Lr + 5 1/0 n
57/24 Cr + 4/2 He ---> _ + 56/26 Fe
40/18 Ar + 4/2 He ---> _ + 1/1 H
