Learn the basics about the differences between different chemical structures, including giant covalent, giant ionic and metallic structures. There are numerous materials and substances that possess giant chemical structures. Some are...

Practice REAL problems from actual past IIT/JEE exams with Professor Dave!

In this video, we're going to learn how diodes work. We're going to start by reviewing the basic properties of diodes, and then we'll move on to discuss how diodes are used in circuits. By the end of the video, you'll have a basic...

Once we get the hang of stoichiometric calculations, we get a curve ball. Limiting reagents? Not all of the reactants will react? We might not get as much product as we expect? Let's practice identifying the limiting reagent, calculating...

A San Diego researcher has developed a way to tag cancer cells for early detection in the blood stream.

Professor Michael Sailor hopes to dramatically change how cancer is treated. He is on a quest to create nanoparticles that...

Learn the basics about allotropes of metalloids and metals, as a part of the overall properties of matter topic. An allotrope is basically a different form of the same element, each with distinct physical and chemical properties. For...

The video is about covalent molecules, their properties and behavior. The video then goes on to discuss polymers, which are formed by the reaction of monomers with a C-C double bond. The video also discusses giant covalent structures,...

Diodes Explained, in this tutorial we look at how diodes work, where diodes are used, why diodes are used, the different types. We look at diodes in half and full bridge rectifiers to convert AC to DC.

In this live-action program viewers will learn Mining is the process of extracting minerals and metals from the earth. Students will come to understand that Minerals are essential to modern technology and that metals and other elements...

Silicates are a particularly complex class of minerals that all contain silica tetrahedra. Let's look at a few of the sub classes of silicates and the minerals in those groups to learn more about silicate structure.
