Introduction
Nuclear decay is a fundamental concept in chemistry and physics that describes the process by which unstable atomic nuclei lose energy and stability. In this article, we will delve into the world of nuclear decay, exploring the different types of decay and the underlying mechanisms that drive them. We will examine the specific case of oxygen decaying to form nitrogen, and identify the type of nuclear decay that occurs in this process.
What is Nuclear Decay?
Nuclear decay is a process in which an unstable atomic nucleus loses energy and stability by emitting radiation. This radiation can take various forms, including alpha particles, beta particles, and gamma rays. The nucleus of an atom is composed of protons and neutrons, which are held together by the strong nuclear force. When a nucleus is unstable, it can undergo a decay process to become more stable.
Types of Nuclear Decay
There are several types of nuclear decay, each with its own unique characteristics and mechanisms. The three main types of decay are:
- Alpha decay: This type of decay occurs when an unstable nucleus emits an alpha particle, which is a high-energy helium nucleus. Alpha decay is typically observed in heavy elements, such as uranium and thorium.
- Beta minus decay: This type of decay occurs when an unstable nucleus emits a beta particle, which is a high-energy electron. Beta minus decay is typically observed in elements with too many neutrons, such as carbon-14.
- Beta plus decay: This type of decay occurs when an unstable nucleus emits a positron, which is the antiparticle of an electron. Beta plus decay is typically observed in elements with too few neutrons, such as nitrogen-13.
- Gamma radiation: This type of decay occurs when an unstable nucleus emits a high-energy photon, which is a type of electromagnetic radiation. Gamma radiation is typically observed in elements that have undergone other types of decay.
The Case of Oxygen Decaying to Form Nitrogen
The equation given in the problem is:
{ {}_8^{15} O \rightarrow {}_7^{15} N + {}_1^0 e \}
In this equation, oxygen-15 decays to form nitrogen-15, emitting a beta particle (electron) in the process. This type of decay is known as beta minus decay.
Why is Beta Minus Decay the Correct Answer?
Beta minus decay occurs when an unstable nucleus has too many neutrons. In the case of oxygen-15, the nucleus has 7 protons and 8 neutrons, which is an unstable configuration. To become more stable, the nucleus emits a beta particle, which is a high-energy electron. This electron is emitted from the nucleus, resulting in the formation of a more stable nucleus with 7 protons and 7 neutrons, which is nitrogen-15.
Conclusion
In conclusion, the type of nuclear decay that occurs when oxygen decays to form nitrogen is beta minus decay. This type of decay is characterized by the emission of a beta particle (electron) from an unstable nucleus, resulting in the formation of a more stable nucleus. Understanding nuclear decay is essential for understanding the behavior of atomic nuclei and the underlying mechanisms that drive chemical reactions.

Nuclear Decay Q&A: Understanding the Fundamentals =====================================================
Introduction
Nuclear decay is a complex and fascinating topic that has been extensively studied in the fields of chemistry and physics. In our previous article, we explored the basics of nuclear decay, including the different types of decay and the underlying mechanisms that drive them. In this article, we will delve deeper into the world of nuclear decay, answering some of the most frequently asked questions about this topic.
Q&A Session
Q: What is the difference between alpha, beta, and gamma radiation?
A: Alpha, beta, and gamma radiation are three types of ionizing radiation that are emitted by unstable atomic nuclei. Alpha radiation consists of high-energy helium nuclei, beta radiation consists of high-energy electrons or positrons, and gamma radiation consists of high-energy photons.
Q: What is the process of radioactive decay?
A: Radioactive decay is the process by which unstable atomic nuclei lose energy and stability by emitting radiation. This radiation can take various forms, including alpha particles, beta particles, and gamma rays.
Q: What is the half-life of a radioactive substance?
A: The half-life of a radioactive substance is the time it takes for half of the original amount of the substance to decay. This is a fundamental concept in nuclear physics and is used to describe the rate of decay of radioactive substances.
Q: What is the difference between beta minus and beta plus decay?
A: Beta minus decay occurs when an unstable nucleus emits a beta particle (electron) to become more stable, while beta plus decay occurs when an unstable nucleus emits a positron (the antiparticle of an electron) to become more stable.
