1. What is Chemistry? - Definition, History & Branches
Known as the central science, chemistry is integral to our understanding of the natural world around us. In this lesson, you'll be introduced to the field of chemistry, learning about its history and its modern applications.
2. 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.
3. 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.
4. 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.
5. 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.
6. 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.
7. Isotopes and Average Atomic Mass
When you drink a glass of water, you are actually drinking a combination of heavy water and light water. What's the difference? Is it harmful? This video will explain the difference between the two types of water and go into detail on the significance of the different isotopes of elements.
8. 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.
9. Diatomic Molecule: Definition & Example
Did you know that diatomic molecules make up the majority of the Earth's atmosphere? Diatomic molecules are made up of two atoms. In this lesson, we will discuss diatomic molecules and go over some examples.
10. What is Atomic Mass? - Definition & Examples
Atomic mass is a characteristic of an atom that is a measure of its size. It is plays a major role in the chemical properties of elements. This article discusses atomic mass and how it is calculated.
11. What is Chromium? - Facts, Foods, Benefits & Side Effects
What do Julia Roberts, broccoli, and dollar bills have in common? The answer is the chemical element chromium. In this lesson we will learn what chromium is, why we need it in our diet and why it is also considered a serious environmental pollutant.
12. What Is Helium? - Definition & Concept
In this lesson, explore how the gas helium was discovered and learn about its properties. Learn how helium is used every day, from inflating party balloons to propelling spacecraft.
13. What is Hydrogen? - Formula, Production & Uses
Hydrogen is the lightest naturally occurring element, and is important in many biological, chemical, and industrial processes. This article discusses hydrogen, its properties, and some of its many uses.
14. What is Iron? - Ore & Explanation
Iron. It has an age, a horse and a man named after it. But what is iron, where does it come from and how do we get it? In this lesson, you will learn about this useful metal.
15. What is Molar Mass? - Definition, Formula & Examples
Compounds have mass, and this is what we call the molar mass. In this lesson, we will discuss the molar mass and go over examples on how to calculate it.
16. What is Nickel? - Definition & Explanation
This lesson focuses on the element nickel. The location of nickel on the periodic table, its atomic structure, chemical, and physical properties are discussed in general terms. This lesson also includes selected applications for nickel that are significant to modern currency and manufacturing.
17. What is Nitrogen? - Cycle& Formula
Nitrogen is a vital element for all living things. This lesson walks through some of the properties of nitrogen, the nitrogen cycle, and other uses of nitrogen.
18. What is Oxygen? - Formula & Levels
Breathe! You've just processed another dose of oxygen. Learn about some different forms of oxygen critical to life on Earth, particularly dioxygen and ozone.
19. What is Silica? - Properties & Definition
Silica is the most abundant mineral in the earth's crust, but you might not know much about it. Quartz, sand, and glass are all made of silica. Learn more about the properties and uses of this plentiful mineral.
20. What is Silicon? - Properties & Uses
Learn more about silicon and its amazing qualities. It is one of the most abundant materials on Earth and has a myriad of uses. After the lesson, a quiz is provided to check your understanding.
21. What is Sodium Hydroxide? - Formula & Reactions
While handling sodium hydroxide can be dangerous, knowledge of sodium hydroxide can be enriching. Learn what sodium hydroxide is, its formula and about some chemical reactions involving sodium hydroxide in this lesson.
22. What is Sodium? - Definition, Facts, Properties & Uses
Sodium is everywhere. It's in your sweat, it's in your food, and it's even in the ocean. But, don't be afraid of this common and useful element. In this lesson, learn about the definition of sodium, its properties and uses and even some cool facts.
23. What is Tungsten? - Definition, Properties & Uses
What's the first thing you do when you walk in a dark room? Turn on the light! But what makes the light bulb emit light? The answer is tungsten. This lesson will help you understand the definition, properties, and uses for this useful element.
