Review of Inorganic Chemistry

From the basic units of matter to complex molecular interactions, inorganic chemistry can help us make sense of the fabric of our existence. Did you know that matter, humans beings included, is composed of mostly empty space? Yet atoms made up of electrons, protons and neutrons, these seemingly insignificant specks that populate that space, make all the difference. As you watch our lessons, you'll understand the beautiful interactions that take place between these building blocks.

What do electrons have to do with an atom's desire for stability, and why do Noble gases have it made? As we explore electron shells, you'll learn about electron sharing as well as the give and take that occurs between atoms. You'll navigate the elements of the periodic table while we touch upon atomic number, atomic nucleus, charge, mass, electronegativity and valence electrons. From there, you'll start to see how it all comes together with chemical bonds: covalent, ionic, polar covalent, hydrogen, intramolecular and intermolecular - you name it; we've got you covered.

Why is life dependent on water? You'll get the answers as we examine water's properties and see how aqueous environments can dissolve even the strongest of chemical bonds. What makes some molecules hydrophilic and others hydrophobic? Prepare to become well-acquainted with hydrogen bonds, exploring how they can keep ice afloat as well as play a powerful role in many biological processes. You'll also trace the forms that energy can take and perhaps pick up a good excuse for how your room got so messy. And, of course, we'll examine reactions, the chemical equilibrium dance that takes place between reactants and products. Thanks for watching!

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?

You may be familiar with the role of electrons in electrical devices, but did you know that electrons also determine the chemical reactivity of everything around you?

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.

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.

Are you confused about how you can tell what kind of bond two atoms will form? This lesson will help you understand the difference between polar and nonpolar covalent bonds as well as how to predict how two atoms will interact.

Have you ever been curious about why table salt dissolves in water? Well, watch this video and amaze your friends with your knowledge of hydrogen bonds and intermolecular interactions.

Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.

Oh no! Your friend Ben just drank chili oil on a dare, and now his mouth is burning. Should he drink the ice water or vegetable oil to cool his mouth? Quick. Watch this lesson if you aren't sure.

The cells in our bodies are in constant flux through the processes of osmosis and diffusion. Learn about how saturation levels force change, and why we're lucky they do.

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.

Need a good excuse for why your room is never clean? Try telling Mom that you're just following one of the laws of thermodynamics. Check out this lesson to learn more.

This short video will explain oxidation-reduction reactions, or redox reactions for short. The focus is on how electrons are transferred during redox reactions. Learn some neat mnemonic devices to help you remember when an atom is oxidizing or reducing.

Halloween glo sticks, firecrackers, table salt and the transport of CO2 waste in the body - what do they all have in common? They are all made possible by chemical reactions.

This lesson covers both strong and weak acids and bases, using human blood as an example for the discussion. Other concepts discussed included conjugate acids and bases, the acidity constant, and buffer systems within the blood.
