In this section, I talk about elements, atoms and how they interact. I deal with two types of bonds: Covalent Bonds and Ionic Bonds. I also talk about pH, chemical reactions and metabolism.

Ionic Bond, Covalent Bond, James Bond, so many bonds! What dictates which kind of bond will form? Electronegativity values, of course. Let's go through each type and what they're all about.

Dutch architectural firm UNStudio has been chosen to design a cable car terminal in Russia that will connect the Russian city of Blagoveshchensk to the Chinese city of Heihe.

Models are great, except they're also usually inaccurate. In this episode of Crash Course Chemistry, Hank discusses why we need models in the world and how we can learn from them... even when they're almost completely wrong....

Mr. Andersen shows you how to name covalent and ionic compounds.

Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress...

In this video students will come to understand the basic difference between ionic and covalent bonding. Viewers will learn that covalent bonds form between non-metallic atoms that share pairs of electrons and covalent bonds form between...

MOT 1944: CALCUTTA (KOLKATA): US TRANSPORT: US Soldiers marking fuel tanks labeled 'Chunking'. US Light tanks parked in line one moving out of area another moving onto railroad flatcar. WWII World War II.

Media outlets around the world went crazy over a 5th grade math exam question in China. But they all missed the real story! The problem actually dates back to French researchers in 1979. In this video I present the real story to the...

In this video lesson, students will learn how to describe the combined area of two squares using consecutive integers. They will explore polynomial identities and how to write expressions to represent the relationship between consecutive...

Learn the basics about covalent bonds, when learning about properties of matter. When similar atoms react, like non-metals combining with other non-metals, they share electrons. This is covalent bonding. Non-metals have shells of...

The angle between two vectors can be found by using the cosine rule in a clever way.

Babies are cute because of their face structure and their sounds. Adult brains find the faces features of babies' faces cute. This signature cute baby face is called Kindchenschema (or baby scheme in English). Our brains seemed to be...

Upon viewing the Forming Bonds video series, students will be able to do the following: Understand that matter is made up of tiny particles called atoms. Explain that atoms consist of many different types of subatomic particles including...

Top climate scientist James Hansen tells the story of his involvement in the science of and debate over global climate change. In doing so he outlines the overwhelming evidence that change is happening and why that makes him deeply...

In this video, the teacher explains how to multiply decimals using fractions. They start by reviewing how to represent fractions using drawings. Then, they demonstrate the common mistake of forgetting to consider the decimal when...

In this video Paul Andersen explains how covalent bonds form between atoms that are sharing electrons. Atoms that have the same electronegativity create nonpolar covalent bonds. The bond energy and bond length can be determined by...
