About This Chapter
Subatomic Particles in the Nucleus - Chapter Summary
In this chapter, our instructors dissect the structure of the atom and then explain radioactive decay using the concepts of parent nucleus, daughter nucleus and half-life. Both beta and alpha particles are introduced, along with their definitions, symbols and unique properties. The use of gamma radiation and its effects on the human body is also presented.
Your study continues with a lesson on the standard model of physics and the definition and uses of one of the fundamental particles in physics, the quark. The concepts of matter, antimatter and the topic of nuclear physics are introduced as well. Once you have completed this chapter, you should be able to:
- Explain the structure of an atom
- Describe the three types of radioactive decay
- Define half-life as it relates to radioactive decay
- Identify the properties of alpha and beta particles
- Illustrate the effects of gamma radiation on the human body
- Outline the standard model of physics and the particles that are part of it
- Differentiate between matter and antimatter
- Detail what nuclear physics is, including the concepts of fusion and fission
These mobile-friendly lessons and quizzes are accessible to you 24 hours a day, seven days a week. Use the chapter tests and lesson quizzes to gauge how well you know the topic or to identify sections that need further study. If you have any questions as you review the lessons, contact one of our instructors for help. Each of our videos, lessons and quizzes has been designed by a professional instructor to ensure your learning experience is interesting and fun.
1. Atomic Number and Mass Number
Atoms are the basic building blocks of everything around you. In order to really understand how atoms combine to form molecules, it's necessary to be familiar with their structure. In this lesson, we'll dissect atoms so we can see just what really goes into those little building blocks of matter.
2. Radioactive Decay: Definition, Formula & Types
In this lesson, we'll discuss radioactive decay and learn the terms parent nucleus, daughter nucleus, and half-life. We'll also examine three types of radioactive decay.
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. Alpha Particle: Definition, Symbol & Properties
This lesson will explain what an alpha particle is and what symbols are used to represent it, and will also describe the properties of alpha particles. A short quiz will follow.
5. Beta Particle: Definition & Symbol
In this lesson, we will learn what a beta particle is and introduce the symbol that represents it. We will also learn about both the dangers and the uses of beta particles.
6. Gamma Radiation: Definition, Uses & Equation
In this lesson you will learn what gamma radiation is. We will explore where it comes from, how we as humans make use of it, as well as its effect on the human body.
7. Standard Model of Particle Physics
After completing this lesson, you will be able to explain what the standard model of physics is, name the particles that are part of the standard model, and some of the things it can't currently explain. A short quiz will follow.
8. What is a Quark? - Definition, Structure & Uses
Quarks are fundamental particles that are used by scientists to explain different types of phenomena. Learn more about them, subsequently testing your knowledge with a quiz.
9. Elementary Particles: Matter vs. Antimatter
All matter (and antimatter!) is made of just a few elementary particles. In this lesson, learn about these elementary particles and what happens when matter and antimatter meet!
10. Nuclear Physics: Nuclear Force & Building Energy
After watching this video, you should be able to explain what nuclear physics is, including the concept of binding energy. You should also be able to explain how fusion and fission work. A short quiz will follow.
