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. P-Block Elements on the Periodic Table: Properties & Overview
Come on a tour of the p-block, an area on the periodic table filled with an incredibly diverse group of elements. Learn what the p-block elements are, discover some of their properties, and then assess your new knowledge with a quiz.
10. Alkali Metal Elements: Properties, Characteristics & Reactions
What happens when you put a chunk of an alkali metal in water? Fire, of course! Learn the characteristics of this interesting chemical family, examine some typical alkali metal reactions, and then quiz yourself on your new knowledge.
11. Alkaline Earth Metals: Definition, Properties & Characteristics
Column 2A of the periodic table is home to the reactive alkaline earth metals. We find these elements in fireworks, vitamins, and even running through our own veins. Learn some properties and characteristics of this group of elements, and then take a quiz.
12. Anion: Definition & Examples
Ions are charged particles that are important for biological and chemical systems. Anions are ions that have a negative charge. This article discusses anions, their properties, and examples of anions in chemistry and nature.
13. Atomic Number: Definition & Symbol
This lesson focuses on an important concept in chemistry and physics known as the atomic number. Atomic umber is defined, and examples from the periodic table of the elements are provided to help students apply the concept.
14. 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.
15. Cation: Definition & Examples
Cations are positively the most positive type of particle. Discover what a cation is, where you can find them, and learn some examples of cations. Then, assess your new knowledge with a quiz!
16. Dmitri Mendeleev & the Periodic Table: Biography, Contribution & Facts
A man of many eccentricities, Dmitri Mendeleev and his contributions to the periodic table are so significant that they have been compared to Darwin and the development of the theory of evolution. Read about this legendary chemist and his role in developing one of the most important tools used in science. Then quiz yourself on your new knowledge.
17. Electronegativity: Definition & Trends
The attraction of electrons is different depending on the element. This degree of attraction is measured by the element's electronegativity. In this lesson, we will discuss electronegativity, its trends in the periodic table, and bonding.
18. Formula for Mass: Definition & Examples
In this lesson you will learn about mass and how it is tied to Newton's Second Law of Motion. You will learn how to calculate mass and how to measure mass through a few examples.
19. Halogens on the Periodic Table: Properties, Reactivity & Uses
Elements are grouped into families on the periodic table based on their chemical and physical properties. In this lesson, you will learn about a unique group known as the halogen family.
20. Hydroxide Ion: Definition & Formula
If the name 'hydroxide' sounds toxic to you, that's good. Hydroxide is a powerful chemical with potentially dangerous properties. Learn the definition and formula of hydroxide, as well as some interesting facts about it, in this lesson.
21. Metals on the Periodic Table: Definition & Reactivity
Look around for a second...how many metallic things can you see? Generally when we think of metals, we think of substances that are shiny and durable; however, they're also in our food and in our bodies. Learn what makes a metal a metal and why metals are special.
22. Negative Charge: Definition & Overview
There are two types of charge, positive and negative. In this lesson, you will learn about how negative charges were assigned to electrons. You will also learn about the properties of negative charges and how they affect other objects near them.
23. Neutrons: Definition & Concept
Neutrons are the big guys of the atom. This lesson explains the structure of the neutron, its properties, and some of its influences on the function of the atom.
24. Noble Gases: Definition, List & Properties
Elements are grouped on the periodic table based on their chemical properties. In this lesson, you will learn about a group of elements known as the noble gases and their unique properties.
25. Nonmetal Elements on the Periodic Table: Definition, Properties, & Reactions
Nonmetal elements are omnipresent and essential for life. Learn about the properties and typical reactions of these important elements, and then assess your new knowledge with a quiz.
26. Oxidation Number: Definition, Rules & Examples
Knowing the ion form of an atom is important when putting together atoms to form a compound. An oxidation number is assigned to an atom to know its ion form. In this lesson, we will go over the rules to assign oxidation numbers to atoms.
27. What is Xenon? - Definition, Uses & Facts
Xenon is an element that exists as a gas at most temperatures and is not very reactive. This lesson looks at some general information about xenon, as well as some of its useful applications.
