Ch 1: Atomic Structure & Fundamentals of Matter

About This Chapter

Watch video lessons and learn some basic concepts related to atomic structure. These lessons use fun and engaging animations and graphics to bring atomic structures to life and help you retain the info easily.

In this chapter, you'll take a look at atomic structures. Our instructor will lead you through lessons that cover early atomic theory and the periodic table. You'll study elements, compounds and molecules. Throughout the chapter, the lessons will continue to build upon the basic ideas of atoms to help you understand all the different related concepts. Some of the things that will be covered include:

  • How to determine atomic number
  • How atoms and ions determine formulas
  • How ionic bonds are formed
  • Nonpolar and polar covalent bonding
  • The octet rule
  • The findings of early atomic theory

VideoObjective
Early Atomic Theory: Dalton, Thomson, Rutherford and Millikan Explore the findings of pioneering atomic scientists John Dalton, J.J. Thomson, Ernest Rutherford and Robert Millikan.
Elements Discover what an element is and how elements are used as building blocks.
The Periodic Table: Properties of Groups and Periods Examine the periodic table and how it is used.
Atomic Number and Mass Number Learn how to determine the number of protons, neutrons and electrons in an atom.
Compounds & Molecules Study how compounds and molecules are built from elements.
Formulas & Ions Analyze how atoms and ions determine formulas.
Understanding Ionic and Hydrogen Bonds: Definitions and Examples Explore ionic and hydrogen bonds.
Understanding Covalent Bonds Discover nonpolar and polar covalent bonding, including how peptide and metallic bonds are examples of covalent bonds.
Covalent Bonding and Electron Shells: Definitions, Relationship & the Octet Rule Examine the octet rule through the relationship between valence electrons and covalent bonding.

What Are Elements?

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.

Atomic Number and Mass Number

2. 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.

The Periodic Table: Properties of Groups and Periods

3. 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.

Ionic Bonds: Definitions and Examples

4. Ionic Bonds: Definitions and Examples

Did you know that when atoms stick together to form molecules, they gain and lose electrons, making them negatively or positively charged? In this lesson, you will learn how cations and anions form one type of chemical bond called an ionic bond.

Polar and Nonpolar Covalent Bonds: Definitions and Examples

5. Polar and Nonpolar Covalent Bonds: Definitions and Examples

Did you know that some types of chemical bonds behave similarly to the way that children play with toys? In this lesson, you will learn about two types of bonds called polar and nonpolar covalent bonds.

Covalent Bonding and Electron Shells: Definitions, Relationship & the Octet Rule

6. Covalent Bonding and Electron Shells: Definitions, Relationship & the Octet Rule

Learn about the different electron shells of atoms as well as the octet rule for valence electrons and how that applies to covalent bonding. Discover the definition of covalent bonding and the relationships between atoms.

Chemical Bonds IV: Hydrogen

7. Chemical Bonds IV: Hydrogen

This lesson defines and discusses important concepts behind hydrogen bonding. You'll learn when and why these bonds occur and which atoms are often involved.

States of Matter: Solids, Liquids, Gases, & Plasma

8. 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.

Common Chemical Reactions and Energy Change

9. Common Chemical Reactions and Energy Change

This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.

Endothermic and Exothermic Reactions

10. Endothermic and Exothermic Reactions

Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.
