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 and determine the values of Y and X in the given equation.

Understanding Alpha Decay

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, resulting in a decrease in the atomic number by two units and a decrease in the mass number by four units. The equation for alpha decay can be represented as:

$$\left(^{A}_{Z}\text{X} \rightarrow ^{A-4}_{Z-2}\text{Y} + ^{4}_{2}\text{He}\right)$$

where A is the mass number, Z is the atomic number, X is the parent nucleus, Y is the daughter nucleus, and He is the alpha particle.

The Given Equation

The given equation is:

$$\left(^{212}_{83}\text{Bi} \rightarrow ^{Y}_{81}\text{Tl} + ^{4}_{X}\text{He}\right)$$

In this equation, Bi is the parent nucleus, Tl is the daughter nucleus, and He is the alpha particle. We need to determine the values of Y and X.

Determining the Value of Y

To determine the value of Y, we need to consider the mass number and atomic number of the daughter nucleus. In alpha decay, the mass number decreases by four units, and the atomic number decreases by two units. Therefore, the mass number of the daughter nucleus is:

$$Y = A - 4$$

$$Y = 212 - 4$$

$$Y = 208$$

The atomic number of the daughter nucleus is:

$$Z = Z - 2$$

$$Z = 83 - 2$$

$$Z = 81$$

However, we already know that the atomic number of the daughter nucleus is 81. Therefore, the value of Y is indeed 208.

Determining the Value of X

To determine the value of X, we need to consider the mass number and atomic number of the alpha particle. The mass number of the alpha particle is 4, and the atomic number is 2. Therefore, the value of X is:

$$X = 2$$

Conclusion

In conclusion, the values of Y and X in the given equation are 208 and 2, respectively. This is consistent with the equation of alpha decay, where the mass number decreases by four units and the atomic number decreases by two units.
