Understanding Nuclear Fission Processes: A Guide to Completing the Equation

Introduction

Nuclear fission is a process in which an atomic nucleus splits into two or more smaller nuclei, releasing a significant amount of energy in the process. This process is a crucial aspect of nuclear physics and has numerous applications in fields such as energy production, medicine, and research. In this article, we will delve into the world of nuclear fission and explore how to complete an equation that represents this process using the periodic table.

The Periodic Table: A Tool for Understanding Nuclear Fission

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. The periodic table is a powerful tool for understanding the properties and behavior of elements, including their nuclear properties. By using the periodic table, we can identify the elements involved in a nuclear reaction and determine the products of the reaction.

**The Equation: $${{ }_{92}^{235} U+{ }0^1 n \rightarrow{ }{56}^{139} Ba+{ }_8^A C+3{ }_0^1 n}$$

The equation represents a nuclear fission process in which a uranium-235 nucleus ($${{ }_{92}^{235} U}$$) is bombarded with a neutron ($${{ }0^1 n}$$), resulting in the formation of a barium-139 nucleus ($${{ }{56}^{139} Ba}$$), a carbon nucleus ($${{ }_8^A C}$$), and three neutrons ($${{ }_0^1 n}$$). The equation is incomplete, and we need to determine the value of the atomic mass ( $A$ ) of the carbon nucleus.

Completing the Equation

To complete the equation, we need to use the periodic table to determine the value of the atomic mass ( $A$ ) of the carbon nucleus. We can start by identifying the elements involved in the reaction and their atomic numbers.

Uranium (U) has an atomic number of 92.
Neutron (n) has an atomic number of 0.
Barium (Ba) has an atomic number of 56.
Carbon (C) has an atomic number of 6.

Next, we need to use the periodic table to determine the atomic mass of the carbon nucleus. We can do this by looking up the atomic mass of carbon on the periodic table. The atomic mass of carbon is 12.01 u (unified atomic mass units).

Determining the Atomic Mass of Carbon

Now that we have identified the atomic number of carbon, we can use the periodic table to determine the atomic mass of the carbon nucleus. We can do this by looking up the atomic mass of carbon on the periodic table. The atomic mass of carbon is 12.01 u.

However, the equation states that the carbon nucleus has an atomic mass of $A$ . To determine the value of $A$ , we need to use the fact that the atomic mass of an element is equal to the sum of the masses of its protons and neutrons.

The atomic mass of carbon is 12.01 u, which is equal to the sum of the masses of its protons and neutrons. Since carbon has 6 protons, the mass of its protons is 6 x 1.007 u = 6.042 u. The mass of its neutrons is 12.01 u - 6.042 u = 5.968 u.

Since the carbon nucleus has an atomic mass of $A$ , we can set up the following equation:

$A$ = 5.968 u + 3 x 1.008 u

Simplifying the equation, we get:

$A$ = 5.968 u + 3.024 u

$A$ = 9.992 u

Conclusion

In conclusion, we have completed the equation that represents a nuclear fission process using the periodic table. We identified the elements involved in the reaction and their atomic numbers, and we used the periodic table to determine the atomic mass of the carbon nucleus. The value of the atomic mass of the carbon nucleus is 9.992 u.

Discussion

Nuclear fission is a complex process that involves the splitting of an atomic nucleus into two or more smaller nuclei. The equation we completed in this article represents a specific type of nuclear fission process, in which a uranium-235 nucleus is bombarded with a neutron, resulting in the formation of a barium-139 nucleus, a carbon nucleus, and three neutrons.

The periodic table is a powerful tool for understanding nuclear fission processes. By using the periodic table, we can identify the elements involved in a nuclear reaction and determine the products of the reaction. In this article, we used the periodic table to complete an equation that represents a nuclear fission process.

Answer

A: $${{ }_{6}^{12} C}$$

B: $${{ }_{0}^{3} n}$$

C: $${{ }_{0}^{0} n}$$

Note

The value of the atomic mass of the carbon nucleus is 12.01 u, not 9.992 u. The correct answer is $${{ }_{6}^{12} C}$$.
