Introduction

Nuclear fission is a process in which an atomic nucleus splits into two or more smaller nuclei, along with the release of energy, neutrons, and gamma radiation. This process is a crucial aspect of nuclear physics and has significant applications in the field of nuclear energy and medicine. In this article, we will delve into the details of nuclear fission reactions, focusing on the complete reaction equations for two specific examples.

Nuclear Fission Reaction A

The first reaction we will analyze is:

${_{92}^{235} \text{U} + {}_0^1 \text{n} \rightarrow {}_{30}^{90} \text{Kr} + {}_{56}^{\wedge} \text{Ba} + 3{}_0^1 \text{n}}$

To balance this reaction, we need to determine the mass number and atomic number of the unknown nucleus, denoted by ${{}_{56}^{\wedge} \text{Ba}}$ .

Balancing the Reaction

Let's start by balancing the mass numbers:

235 (mass number of U) + 1 (mass number of n) = 90 (mass number of Kr) + ${\wedge}$ (mass number of Ba) + 3 (mass number of n)

Simplifying the equation, we get:

236 = 90 + ${\wedge}$ + 3

Subtracting 90 and 3 from both sides, we get:

${\wedge}$ = 143

Now, let's balance the atomic numbers:

92 (atomic number of U) + 0 (atomic number of n) = 30 (atomic number of Kr) + 56 (atomic number of Ba) + 0 (atomic number of n)

Simplifying the equation, we get:

92 = 30 + 56

Subtracting 30 and 56 from both sides, we get:

0 = 0

This confirms that the atomic numbers are balanced.

Conclusion

The complete reaction equation for the first example is:

${_{92}^{235} \text{U} + {}_0^1 \text{n} \rightarrow {}_{30}^{90} \text{Kr} + {}_{56}^{143} \text{Ba} + 3{}_0^1 \text{n}}$

Nuclear Fission Reaction B

The second reaction we will analyze is:

${_{98}^{239} \text{Pu} + {}_0^1 \text{n} \rightarrow {}_{54}^{137} \text{Xe} + {}_{44}^{102} \text{Ru} + 2{}_0^1 \text{n}}$

To balance this reaction, we need to determine the mass number and atomic number of the unknown nucleus, denoted by ${{}_{44}^{102} \text{Ru}}$ .

Balancing the Reaction

Let's start by balancing the mass numbers:

239 (mass number of Pu) + 1 (mass number of n) = 137 (mass number of Xe) + 102 (mass number of Ru) + 2 (mass number of n)

Simplifying the equation, we get:

240 = 137 + 102 + 2

Subtracting 137, 102, and 2 from both sides, we get:

-1 = 0

This indicates that the mass numbers are not balanced. To balance the reaction, we need to adjust the mass number of the unknown nucleus.

Adjusting the Mass Number

Let's adjust the mass number of the unknown nucleus by 1 unit:

${{}_{44}^{103} \text{Ru}}$

Now, let's rebalance the reaction:

239 (mass number of Pu) + 1 (mass number of n) = 137 (mass number of Xe) + 103 (mass number of Ru) + 2 (mass number of n)

Simplifying the equation, we get:

240 = 137 + 103 + 2

Subtracting 137, 103, and 2 from both sides, we get:

0 = 0

This confirms that the mass numbers are balanced.

Conclusion

The complete reaction equation for the second example is:

${_{98}^{239} \text{Pu} + {}_0^1 \text{n} \rightarrow {}_{54}^{137} \text{Xe} + {}_{44}^{103} \text{Ru} + 2{}_0^1 \text{n}}$
