Complete the folowing reactions:
`(i) ""_(90)""^(234)Thto....7""_(2)""^(4)He+6""_(-1)beta""^(0)`
`(i) ""_(92)""^(235)U+""_(0)n""^(1)to....+""_(52)""^(137)Te+""_(40)""^(97)Zr`
(iii) `""_(34)""^(84)Seto2""_(-1)r""^(0)+....`

Answer 1

(i) `""_(90)""^(234)Thto""_(82)""^(206)M+7""_(2)He""^(4)+6 ""_(-1)beta""^(0)`
Mass no. of element `(M)= 234-7xx4=206`
Atomic no. of element (M)
`=90-[7xx2+6xx(-1)]`
`=90-(14-6)=82`
(ii) `""_(92)""^(235)U+""_(0)n""^(1)to""_(52)Te""^(137)+""_(40)Zr""^(97)+2""_(0)n""^(1)`
(iii) `""_(31)""^84Seto 2""_(-1)e""^(0)+.""_(36)Kr""^(84)`
