About This Chapter
ORELA Chemistry - Properties of Matter - Chapter Summary
Determine how much you remember about the properties of matter and identify the areas in which you need greater comprehension. This chapter's video lessons will guide you in understanding the importance of elements and how they can be written in symbols. The mixtures and pure substances of properties are outlined, and the lessons also explore the compounds and molecules that can be built from elements. Expand your knowledge of these and other topics in order to successfully answer pertinent questions on the ORELA Chemistry examination. Review these lessons so that you can:
- Define and understand elements as building blocks of molecules and compounds
- Describe the processes of chromatography, distillation and filtration
- Use conduction and precipitation to identify the chemicals in a solution
- Explain the characteristics of physical and chemical properties
- Distinguish between intensive and extensive properties of matter
- Learn more about chemical and physical changes in matter
- Explore different types of radioactive decay
- Discuss half-life and mass-energy conversion

ORELA Chemistry - Properties of Matter Objectives
The ORELA Chemistry examination is computer based, and it contains five content domains. Your expertise on the properties of matter can be displayed during the Matter and Atomic Structure content domain of the examination. This domain accounts for 18% of the entire test score. It will ensure your ability to assess changes in matter and to understand the properties of compounds, mixtures and elements. You will have three hours and 45 minutes to answer the examination's 150 multiple-choice questions as you pursue a teaching certification in Oregon.
1. 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.
2. How Compounds and Molecules Are Built From Elements
Did you know that elements are like people and have different personalities? A few elements are very shy and love to be left alone. Others are very social and prefer to hang out with friends. In this lesson we will discuss how elements build molecules and compounds.
3. Chromatography, Distillation and Filtration: Methods of Separating Mixtures
What are some ways that mixtures can be separated? Watch this video to explore several examples of ways you can separate a mixture into its individual components.
4. How to Identify Chemicals in Solution: Test Methods & Materials
Do you have a mysterious solution sitting around? Learn to identify it using one of the following methods: through precipitation, using conduction, using a flame test, using an acid-base indicator and observing the color of the solution.
5. Matter: Physical and Chemical Properties
How are substances identified? There are two major ways we can describe a substance: physical properties and chemical properties. Learn about how chemists use properties to classify matter as either a mixture or a pure substance.
6. Examples of Intensive & Extensive Properties of Matter
This lesson will explore some examples of intensive and extensive properties to help you identify them more easily in the future. At the end of this lesson, you should be able to define intensive and extensive properties and provide examples.
7. States of Matter and Chemical Versus Physical Changes to Matter
The world around us is constantly changing. Chemists put those changes into two main categories: physical changes and chemical changes. This lesson will define and provide examples of each.
8. 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.
9. 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.
10. 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.
