The Periodic Table: Properties of Groups and Periods

1. 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.

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.

Average Atomic Mass: Definition & Formula

3. Average Atomic Mass: Definition & Formula

Did you know there are three types of oxygen? Atoms of elements have different versions of each other called isotopes. In this lesson, we will learn how to find the average atomic mass of the elements from its isotopes.

What Are Isotopes? - Definition, Types & Examples

4. What Are Isotopes? - Definition, Types & Examples

Not all atoms of an element are identical - atoms of the same element can have different numbers of neutrons. These different versions of the same element are called isotopes. In this lesson, we will discuss the examples and types of isotopes.

Types of Radioactive Decay and Their Effect on the Nucleus

5. 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.

Half-life: Calculating Radioactive Decay and Interpreting Decay Graphs

6. 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.

What Is a Subatomic Particle? - Definition & Mass

7. What Is a Subatomic Particle? - Definition & Mass

A subatomic particle is a particle smaller than an atom. Learn more about how to identify subatomic particles through several examples, and test your knowledge with quiz questions.

Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table

8. Atomic and Ionic Radii: Trends Among Groups and Periods of the Periodic Table

Atoms are VERY tiny. How do we measure their size? This lesson will explain how the size of an atom is measured and teach you how to predict the relative size of an atom based on where it is located on the periodic table.

Ionization Energy: Trends Among Groups and Periods of the Periodic Table

9. Ionization Energy: Trends Among Groups and Periods of the Periodic Table

Do you know someone who has undergone radiation as a form of cancer treatment? Have you ever thought about why X-rays have health risks? Watch the video to find out what these types of radiation are really doing to atoms, define ionization energy and identify ionization trends on the periodic table.

Electronegativity: Trends Among Groups and Periods of the Periodic Table

10. Electronegativity: Trends Among Groups and Periods of the Periodic Table

How is fluorine like a child that doesn't share his or her toys? Find out in this video on electronegativity where we will discuss group and periodic trends among the elements.

Valence Electrons and Energy Levels of Atoms of Elements

11. Valence Electrons and Energy Levels of Atoms of Elements

The periodic table contains a wealth of information. This lesson will explain how to use it to quickly determine the most useful information about the most important electrons. We will be focusing our discussion on valence electrons and energy levels.

Electron Configurations in Atomic Energy Levels

12. Electron Configurations in Atomic Energy Levels

This lesson will explain what the electrons are doing inside the atom. Tune in to find out how we specify where they are located and how this location description will help us predict an element's properties.

Assigning Oxidation Numbers to Elements in a Chemical Formula

13. Assigning Oxidation Numbers to Elements in a Chemical Formula

Learn the importance of oxidation in chemical reactions. Discover the rules for assigning oxidation numbers in both covalent compounds and ionic compounds. Learn how to assign the oxidation number for each element in a chemical formula.

Physical & Chemical Properties of Elements: Metals, Nonmetals & Metalloids

14. Physical & Chemical Properties of Elements: Metals, Nonmetals & Metalloids

Elements are elementary! They are simple substances that cannot be broken down. Learn how each element has its own unique set of physical and chemical properties, and how we use those properties to categorize them as metals, nonmetals, and metalloids.
