About This Chapter
Basic Principles of Matter & Energy - Chapter Summary
Whether you're interested in learning about the basic principles of matter and energy or want to refresh your existing knowledge, this chapter can help! Explore entertaining videos developed by top instructors to get a wealth of information about matter, atoms, elements and much more. Once you've taken time to examine this chapter, you will be ready to:
- Identify and describe the four states of matter
- Define the atom, and differentiate between the atoms that make up the elements of the periodic table
- Discuss the meaning of elements and discover how they are written as symbols
- Explain how molecules and compounds are built from elements
- Share the meaning and types of isotopes
Each lesson in this chapter is available as a short video or full transcript. Watch the videos if you enjoy learning with help from engaging visual effects, and read the transcripts if you like to print your materials and take additional notes. Also, take advantage of clickable timelines that enable you to identify and skip to key topics within the videos. With each lesson is a short quiz you can use to assess your understanding of matter and energy. If you answer a question incorrectly, simply click the link next to the answer to revisit the related portion of the video lesson.
1. States of Matter: Solids, Liquids, Gases & Plasma
Learn the four states of matter in the universe: solid, liquid, gas and plasma. Learn about the differences in shape and volume among the four states, which of the states is the most common and why plasma conducts electricity.
2. The Atom
Tune into this lesson to find out what matters about matter. What exactly is an atom? And, how do the atoms that make up the elements in the periodic table differ from one another?
3. What Are Elements?
Look around you. What do you see? Elements are everywhere. They are the building blocks of all matter on Earth. In this lesson, we will discuss what an element is, how elements are written as symbols, and how elements are the building blocks of all matter.
4. How Compounds and Molecules Are Built From Elements
Did you know that elements are somewhat like people and have different personalities? Some elements like to be left alone. Others prefer to hang out with friends. We'll discuss how elements build molecules and compounds and how these can be classified.
5. What Are Isotopes? - Definition, Types & Examples
Not all atoms of an element are identical - atoms of the same element can have different numbers of neutrons. These different versions of the same element are called isotopes. In this lesson, we will discuss the examples and types of isotopes.
