Understanding Nuclear Fission and the Periodic Table

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 often used in nuclear reactors and atomic bombs. The periodic table is a tabular arrangement of the known chemical elements, organized by their atomic number (number of protons in the nucleus), electron configuration, and recurring chemical properties. In this article, we will use the periodic table to balance a nuclear fission equation.

The Given Nuclear Fission Equation

The given nuclear fission equation is:

{ \begin{array}{l} {}_{92}^{235} U + {}_0^1 n \rightarrow {}_{56}^{139} Ba + {}_8 C + 3{}_0^1 n \\ \end{array} \}

In this equation, we have:

Uranium-235 ( ${}_{92}^{235} U$ ) as the reactant
A neutron ( ${}_0^1 n$ ) as the reactant
Barium-139 ( ${}_{56}^{139} Ba$ ) as one of the products
Carbon-8 ( ${}_8 C$ ) as one of the products
Three neutrons ( $3{}_0^1 n$ ) as the products

Balancing the Nuclear Fission Equation

To balance the equation, we need to ensure that the number of protons (atomic number) and the number of neutrons (mass number) are the same on both the reactant and product sides.

Step 1: Identify the Atomic Numbers and Mass Numbers

Uranium-235: Atomic number = 92, Mass number = 235
Neutron: Atomic number = 0, Mass number = 1
Barium-139: Atomic number = 56, Mass number = 139
Carbon-8: Atomic number = 6, Mass number = 8
Three neutrons: Atomic number = 0, Mass number = 3

Step 2: Balance the Atomic Numbers

The atomic number of the reactants is 92 (Uranium) + 0 (Neutron) = 92. The atomic number of the products is 56 (Barium) + 6 (Carbon) = 62. To balance the atomic numbers, we need to add a particle with an atomic number of 10 to the products.

Step 3: Balance the Mass Numbers

The mass number of the reactants is 235 (Uranium) + 1 (Neutron) = 236. The mass number of the products is 139 (Barium) + 8 (Carbon) + 3 (Neutrons) = 150. To balance the mass numbers, we need to add a particle with a mass number of 86 to the products.

Step 4: Identify the Particle with the Correct Atomic and Mass Numbers

Using the periodic table, we can identify the particle with an atomic number of 10 and a mass number of 86. This particle is Neon-86 ( ${}_{10}^{86} Ne$ ).

Step 5: Write the Balanced Equation

The balanced nuclear fission equation is:

{ \begin{array}{l} {}_{92}^{235} U + {}_0^1 n \rightarrow {}_{56}^{139} Ba + {}_6^8 C + {}_{10}^{86} Ne + 3{}_0^1 n \\ \end{array} \}

Conclusion

In this article, we used the periodic table to balance a nuclear fission equation. We identified the reactants and products, balanced the atomic numbers and mass numbers, and added a particle with the correct atomic and mass numbers to the products. The balanced equation is:

{ \begin{array}{l} {}_{92}^{235} U + {}_0^1 n \rightarrow {}_{56}^{139} Ba + {}_6^8 C + {}_{10}^{86} Ne + 3{}_0^1 n \\ \end{array} \}

This equation shows that the nuclear fission of Uranium-235 produces Barium-139, Carbon-8, Neon-86, and three neutrons.
