Physical Property of Matter: Definition & Examples

1. Physical Property of Matter: Definition & Examples

Every time you look at an object, you observe its properties. In this lesson, you will learn about the physical properties of matter so you can identify them in the future.

What Is a Chemical Property of Matter? - Definition & Examples

2. What Is a Chemical Property of Matter? - Definition & Examples

All matter is characterized based on its properties. In this lesson, you will learn about the different chemical properties of matter and ways to identify them.

Examples of Intensive & Extensive Properties of Matter

3. 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.

States of Matter and Chemical Versus Physical Changes to Matter

4. 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.

The Atom

5. 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?

Atomic Number and Mass Number

6. 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.

Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

7. Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan

Imagine firing a bullet at a piece of tissue paper and having it bounce back at you! You would probably be just as surprised as Rutherford when he discovered the nucleus. In this lesson, we are going to travel back in time and discuss some of the major discoveries in the history of the atom.

The Bohr Model and Atomic Spectra

8. 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.

Matter: Physical and Chemical Properties

9. 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.

Pure Substance in Chemistry: Definition, Properties & Examples

10. Pure Substance in Chemistry: Definition, Properties & Examples

This lesson introduces the concept of the pure substance. The impact of purity on the physical and chemical properties are discussed and several examples are explored along the way.

What Are Elements?

11. 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.

Understanding the Relationships between Elements, Molecules & Compounds

12. Understanding the Relationships between Elements, Molecules & Compounds

Everything on Earth is made of atoms, and sometimes they combine to form new groups of atoms. The sky is the limit when it comes to these combinations, which account for the vast number of things we find in our natural world.

Chemical Bonds: Ionic vs. Covalent

13. Chemical Bonds: Ionic vs. Covalent

Atoms make up everything on Earth, and chemical bonds are what hold those atoms together. In this lesson, we'll discuss two very important types of chemical bonds: covalent and ionic.

What Is a Chemical Compound? - Definition & Examples

14. What Is a Chemical Compound? - Definition & Examples

Very few single chemical elements are encountered in everyday life. In this lesson, you will learn about chemical compounds through some examples to gain a better understanding of what they are and how they form.

Acids and Bases

15. Acids and Bases

Have you ever wondered how we measure the acidity of liquids? Check out this lesson to see how acids and bases are measured on a pH scale and how they relate to neutral solutions, such as water.

The Periodic Table: Properties of Groups and Periods

16. The Periodic Table: Properties of Groups and Periods

How is the periodic table like the map you used on your last road trip? In this lesson, you will be introduced to the periodic table, the road map of chemists. We will discuss how the elements are organized and how you can use this organization to identify some of their major physical properties.

What is a Chemical Formula? - Definition, Types & Examples

17. What is a Chemical Formula? - Definition, Types & Examples

Chemical formulas provide a lot of information about chemical substances, such as how many and what atoms they are made of, as well as the way the atoms are arranged. In this lesson, we'll discuss the different types of chemical formulas.

Lewis Dot Structures: Resonance

18. Lewis Dot Structures: Resonance

In this lesson, we'll review Lewis dot structures and how to draw them. Then, learn about resonance and resonance structures for molecules and polyatomic ions. Afterwards, assess your new knowledge with a quiz.

Basic Properties of Chemical Reactions

19. Basic Properties of Chemical Reactions

Learn how about the various components of a chemical reaction, and how those components function. Use this lesson to understand the basic properties of different kinds of chemical reactions.

Creating Mixtures by Combining Elements & Compounds

20. Creating Mixtures by Combining Elements & Compounds

Do you really know what's in your tap water? It's not just water - it's a mixture of many different things. In fact, most things are mixtures of different elements and compounds that are physically joined together.

Creating Solutions by Combining Elements & Compounds

21. Creating Solutions by Combining Elements & Compounds

When elements and compounds physically combine, we get mixtures. But sometimes we can't tell just by looking at something that it's a mixture because the components are so well mixed. When this happens, we have solutions.

What is Suspension in Science? - Definition, Types & Examples

22. What is Suspension in Science? - Definition, Types & Examples

Have you ever seen dust particles floating in a stream of sunlight? The dust you see in the air is an example of suspension. Discover this fascinating mixture, explore a special type of suspension, and see examples in this lesson.

Solubility and Solubility Curves

23. Solubility and Solubility Curves

Learn what solubility is as well as the definitions of 'saturated,' 'unsaturated' and 'supersaturated.' Learn how to determine the solubility of a substance in water by using a solubility curve. Discover the effects of pressure and temperature on the solubility of liquids, solids and gases.
