Homework Answers
In a nuclear reaction the sum of mass numbers of reactants should be equal to the sum of mass numbers of products.
Sum of mass number of reactants = 235+1= 236
Sum of mass number of products = 137+ 3= 140
Mass number of missing product = 236-140 = 96
Also the sum of charges is also balanced ( the number of protons)
Sum of charges of reactants = 92 + 0= 92
Sum of charges of products = 55 + 0= 55
Charge ( number of protons) of the missing product = 92-55= 37
So the answer is Option 4th. ( Rb)
