Praxis Biology & General Science: Physics Review: Atomic and Nuclear Physics - Chapter Summary

Let these lessons show you how to balance a nuclear equation. Video instructors help you understand all the scientific terminology, introduce you to key historical research, and walk you through important theories to help you understand topics in atomic and nuclear physics that come up on the Praxis science subject test. Short, 5-question quizzes accompany each lesson, so you can gauge your understanding of the subject material. Lessons you'll find in this chapter include:

  • The Bohr Model and Atomic Spectra
  • Types of Radioactive Decay and Their Effect on the Nucleus
  • Balancing Nuclear Equations & Predicting the Product of a Nuclear Reaction
  • Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs
  • Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy
  • Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

Praxis Biology & General Science: Objectives

The Praxis Biology & General Science exam is used to determine your eligibility for licensing as a general/physical science or biology teacher. The exact requirements for licensing or certification, including the minimum score you'll need to be eligible, vary by state.

The exam consists of 120 multiple-choice questions. Physics accounts for about ten percent of the exam, or 12 questions. These 12 questions might cover:

  • Atomic and nuclear physics
  • Electricity and magnetism
  • Energy
  • Environmental issues related to physics
  • Mechanics
  • Optics and wave phenomena

The Bohr Model and Atomic Spectra

1. The Bohr Model and Atomic Spectra

Do you ever wonder where light comes from or how it is produced? In this lesson, we are going to use our knowledge of the electron configurations and quantum numbers to see what goes on during the creation of light.

Types of Radioactive Decay and Their Effect on the Nucleus

2. 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.

Balancing Nuclear Equations & Predicting the Product of a Nuclear Reaction

3. 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.

Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

4. 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.

Mass-Energy Conversion, Mass Defect and Nuclear Binding Energy

5. 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.

Fusion, Fission, Carbon Dating, Tracers & Imaging: Applications of Nuclear Chemistry

6. 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.
