1. 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?
2. 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.
3. 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.
4. Ions: Predicting Formation, Charge, and Formulas of Ions
Learn how ions are formed using the octet rule. Use the periodic table to predict the charge an atom will have when it becomes an ion. Learn whether an ion is a cation or anion and how to write the formula depending on what charge the ion has.
5. 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.
6. Chemical Bonds I: Covalent
Mom always said that sharing is caring. This lesson will explore how electrons affect the chemical reactivity of atoms and specifically the merits of sharing electrons.
7. Chemical Bonds II: Ionic
Did you know that the scientific name for table salt is sodium chloride? Find out how sodium and chlorine atoms come together to form your favorite seasoning.
8. 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.
9. 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.
10. 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.
11. First Law of Thermodynamics: Law of Conservation of Energy
This video describes the first law of thermodynamics. Several examples of the application of this law are discussed. The significance of the law and its practical application are discussed as well.
