Introduction

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, which consists of two protons and two neutrons. This process is a key aspect of nuclear physics and has significant implications for our understanding of the behavior of atomic nuclei. In this article, we will delve into the equation of alpha decay, specifically the reaction $${ }{83}^{212} \text{Bi} \longrightarrow { }{X}^{Y} \text{Tl} + { }_2^4 \text{He}$$, and determine the values of $Y$ and $X$ .

Understanding Alpha Decay

Alpha decay is a process in which an unstable atomic nucleus emits an alpha particle, resulting in a more stable nucleus. The alpha particle is essentially a helium nucleus, consisting of two protons and two neutrons. This process is a key aspect of nuclear physics and has significant implications for our understanding of the behavior of atomic nuclei.

In alpha decay, the parent nucleus (in this case, bismuth-212) undergoes a transformation, emitting an alpha particle and resulting in a daughter nucleus (in this case, thallium). The alpha particle is emitted from the nucleus, resulting in a decrease in the atomic number (number of protons) and mass number (total number of protons and neutrons) of the parent nucleus.

Balancing the Equation

To determine the values of $Y$ and $X$ , we need to balance the equation of alpha decay. This involves ensuring that the atomic numbers (number of protons) and mass numbers (total number of protons and neutrons) are conserved on both sides of the equation.

The atomic number of bismuth (Bi) is 83, and the mass number is 212. The alpha particle has an atomic number of 2 (two protons) and a mass number of 4 (two protons and two neutrons). The daughter nucleus, thallium (Tl), has an unknown atomic number ( $X$ ) and mass number ( $Y$ ).

Conservation of Atomic Numbers

The atomic number of the parent nucleus (bismuth) is 83. The alpha particle has an atomic number of 2, which is subtracted from the parent nucleus, resulting in a decrease of 2 in the atomic number of the daughter nucleus. Therefore, the atomic number of the daughter nucleus ( $X$ ) is:

X = 83 - 2 = 81

Conservation of Mass Numbers

The mass number of the parent nucleus (bismuth) is 212. The alpha particle has a mass number of 4, which is subtracted from the parent nucleus, resulting in a decrease of 4 in the mass number of the daughter nucleus. Therefore, the mass number of the daughter nucleus ( $Y$ ) is:

Y = 212 - 4 = 208

Conclusion

In conclusion, the values of $Y$ and $X$ in the equation of alpha decay $${ }{83}^{212} \text{Bi} \longrightarrow { }{X}^{Y} \text{Tl} + { }_2^4 \text{He}$$ are 208 and 81, respectively. This demonstrates the importance of balancing the equation of alpha decay to determine the values of the atomic numbers and mass numbers of the parent and daughter nuclei.
