1. What Are Elements?
An element is a unique type of matter which cannot be separated into parts that are different from the initial element. Learn how elements are represented through symbols, the particles (atoms) that make up elements, and how elements can combine to create different items in the real world.
2. The Foundational Elements of Life
Living things are complex products of their environments. They are made of a number of different natural elements, many of which are essential to survival. Because of this, they are considered foundational elements and they support life on Earth as we know it.
3. The Atom
Atoms are the smallest unit of matter, the physical substance that all things are composed of. Understand the three subatomic particles that make up atoms--protons, electrons, and neutrons--and how to define the atomic number of an element on the periodic table.
4. The Electron Shell
An outer shell, known as the electron shell, surrounds the nucleus of an atom. Take an in-depth look at the structure of an atom and its electron shell, and the different energy levels in the atomic structure.
5. Chemical Bonds I: Covalent
Learn how an atom shares electrons and form covalent bonds. Explore topics such as how valence electrons are formed, how molecules are made, how a covalent bond is made, the making of double and triple bonds, and the structure of a molecule.
6. Chemical Bonds II: Ionic
An ionic bond occurs when a single valence electron is given to an atom with only seven valence electrons to complete its outer electron shell. Discover key information about valence electrons, electronegativity, elements such as sodium and chlorine, and the process of creating ionic bonds.
7. Chemical Bonds III: Polar Covalent
Polar covalent bonds are chemical bonds that result from unequal electron sharing due to the different electronegativity between two atoms. Learn about polar covalent bonds, nonpolar covalent bonds, and ionic bonds.
8. Chemical Bonds IV: Hydrogen
A hydrogen bond, which is necessary to form water, is and also an intermolecular force formed when a hydrogen atom in a polar molecule is joined with an electronegative atom of another polar molecule. Learn about intramolecular forces, intermolecular forces, and which atoms are typically involved in the formation of chemical bonds like hydrogen.
9. Properties of Water
Hydrogen bonds attribute to water's unique qualities. Through the examples of ice, climate temperature, and sweat, this lesson explores how density, states of matter, specific heat, cohesion, and adhesion impact the properties of water.
10. Solutions, Solutes, and Solvents
Solutions are homogeneous mixtures of two or more substances in which the solvent does the dissolving, while the solute is the solvent substance being dissolved. Explore the definitions and usage of solutions, solutes, and solvents.
11. Osmosis, Diffusion and Saturation
Particles in a solution can move through different states of matter through the processes of osmosis and diffusion. Learn about the concepts of osmosis, diffusion, and saturation, and how they affect the solubility of particles and the movement of molecules.
12. Acids and Bases
Acids are solutions that are below 7 on the pH scale, and bases are solutions that are above 7 on the pH scale. Discover the key differences between acids and bases and how to find a pH level.
13. The Laws of Thermodynamics
The first law of thermodynamics says energy can be converted but not created nor destroyed, while the second law of thermodynamics states that not all energy can be used and increases over time. Learn about the laws of thermodynamics and find examples of how to apply thermodynamics to everyday tasks.
14. Basic Properties of Chemical Reactions
Whenever molecules get together and form a new substance it is a chemical reaction. Explore how chemical reactions occur and learn about reactants and products, chemical equilibrium, and the differences between endothermic and exothermic reactions.
15. Redox (Oxidation-Reduction) Reactions: Definitions and Examples
Redox reactions or oxidation-reduction reactions are chemical reactions that involve the transfer of electrons from one reactant to another. Learn about the process of oxidation-reduction reactions and find different examples of reactions between oxidizing and reducing agents.
16. Hydrolysis and Dehydration: Definitions & Examples
Water is an important component of cellular processes. Two of these processes, dehydration and hydrolysis, help your body build large molecules from small ones and break down large ones into usable components.
17. What Are Ionic Compounds? - Definition, Examples & Reactions
Ionic compounds are a common, yet special type of chemical compound. In this video lesson, you will learn about their formation and structure and see examples of compounds formed by ions.
18. Anabolism and Catabolism: Definitions & Examples
Metabolism breaks down large molecules like food into usable energy. This energy drives bodily processes critical to survival. In this video lesson, you will learn about the two forms of metabolism that break down and build up molecules and see examples of each.
19. Weak Acids, Weak Bases, and Buffers
Weak acids and weak bases are responsible for maintaining the proper pH in human blood. Explore weak acids, weak bases, and buffers, and discover why they are essential to good health.
20. Saponification: Definition, Process & Reaction
If you are in the soap making business, saponification is a very familiar process. Continue reading to learn about this organic reaction and its mechanism. Explore why this process is useful in making handmade soap.
21. Hydrophilic: Definition & Interaction
Hydrophilic materials are compounds or molecules that dissolve in water, like sugar and salt for example. Explore the definition and interaction of hydrophilic materials and discover what makes a molecule hydrophilic and what makes ions and sugars hydrophilic.
