About This Chapter
Praxis Chemistry: Nuclear Structure - Chapter Summary
The chapter contains six lessons detailing a broad range of nuclear structure-related topics in the chemistry field. The following aspects of nuclear structure will be taught in this chapter:
- Characteristics of alpha and beta particles and gamma radiation
- Types of radioactive decay and their impact on the nucleus
- Nuclear equations and nuclear reactions
- Half-life and radioactive decay
- Mass-energy conversion, mass defect and nuclear binding energy
- Nuclear chemistry applications
The strategies you'll learn in the videos will help you to combine your practical knowledge of chemistry with test-taking skills. The engaging instruction in each lesson makes each concept easy to understand.
Praxis Chemistry: Nuclear Structure Objectives
You'll have two hours to take the whole Praxis Chemistry: Content Knowledge test. The entire test has 100 questions. The portion of the test dealing with nuclear structure is in the Atomic and Nuclear Structure section, which has 10 questions and makes up 10% of the test. When you take the self-assessment quizzes, you get to test you efficiency on the forms of questions you'll find on the exam.
The purpose of the Praxis Chemistry: Content Knowledge exam is to determine how well you know material that would be taught by a novice secondary school chemistry teacher. Before taking this exam, individuals usually complete at least an undergraduate program in chemistry and education studies. Several states require the Praxis exams as part of their teacher licensure process, and if you're applying for a professional licensure through an association or organization, they may also use the test scores.
1. Types of Radioactive Decay and Their Effect on the Nucleus
What is meant by the term 'radioactive'? In this lesson we will break down the three main types of nuclear decay particles and discuss their composition, their effect on the nucleus, and their applications.
2. Balancing Nuclear Equations & Predicting the Product of a Nuclear Reaction
When a radioactive particle gives off radiation, what happens to the particle? This lesson will explain the three major types of radiation and what effect they have on the decaying atom.
3. Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs
What causes a radioactive particle to decay? We'll never really know, but our best guess lies in probability. In this lesson, we are going to focus on the half-life, a way of measuring the probability that a particle will react.
4. Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy
When you hear the term 'nuclear power,' what comes to mind? Do you know where that energy and power is coming from? In this lesson, we are going to zoom in on the nucleus of a helium atom to explain how something as small as a nucleus can produce an extremely large amount of energy.
5. Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry
What can the sun do that we can't? How do carbon atoms 'date'? Are radioactive isotopes helpful in the medical field? The answers to these questions can be found in this lesson on the applications of nuclear chemistry.
