What is the difference between a molecule and a compound? What are the main types of chemical bonds? In this video, we will be answering those questions and more.

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....

In this video Paul Andersen describes the structure and explains the properties of molecular solids. High intramolecular forces hold electrons and reduce conductivity, whereas low intermolecular forces decrease the melting point. ...

Valence Bond (VB) theory explains how chemical bonds form through the overlap of atomic orbitals, where electron pairs are shared between atoms. The key concepts include: Atomic Orbital Overlap: Bonds form when atomic orbitals from...

Covalent bonds are very strong can be used to make a range of substances from the very small 'Simple Molecular Substances' to the large 'Giant Covalent Structures'. Learn how their properties differ and why!

This lesson will discuss the rules for writing the names and chemical formulae of covalent molecules and covalent networks. Definitions included: compound, ionic compound, covalent compound, covalent bond, electronegativity, molecular...

In this video, you'll master bond dipoles in minutes – Chemistry Made Simple! 🌟 Dive into the fascinating world of bond dipoles and learn how to identify these crucial elements in various molecules. Understanding bond dipoles is...

We've learned about ionic and covalent bonds, so we understand the interactions that will occur between a metal and a nonmetal, or between two nonmetals. But what about two metals? Metallic bonding! This ends up being sort of like ionic...

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,...

Double and triple bonds involve the sharing of two or three pairs of electrons, providing additional stability and influencing molecular properties like rigidity and reactivity

Chemical bonding explains how atoms combine to form molecules. It involves forces like ionic, covalent, and metallic bonds that hold atoms together, dictating the physical and chemical properties of substances.

What's with all these shapes? Let's practice assigning hybridization, electron-domain geometry, and molecular geometry. Octahedral! Tetrahedral! Linear! Pyramids and see-saws and what not! Chemistry is fun, isn't it?

We've already learned about VSEPR theory, and how to use it to predict the shapes of various molecules. But we didn't cover all of the molecular geometries for certain hybridizations, and we didn't talk about bond angles, so let's do...

This video discusses covalent bonding in chemistry. The presenter starts by explaining that atoms or elements want to have a full outer shell of electrons for stability. They then use examples of how non-metals like fluorine and oxygen...

Video on QM of Atoms which may clarify some concepts:    • The Quantum Mechanical model of an atom. W...  

Why do atoms combine to form molecules? The quantum mechanics of chemical bonds and chemistry....

Beautiful Bonds: The World of Covalent and Metallic Solids

Covalent solids, also known as network solids, are materials with atoms bonded together in a continuous network by covalent bonds, resulting in large, rigid structures....

Molecular Matters: Polar and Non-Polar Solids

Polar molecular solids are crystalline solids with a permanent dipole moment due to differences in electronegativity between atoms. These solids have strong dipole-dipole...

Covalent bonds form when atoms share electrons to complete their valence shells, creating strong and directional interactions.

Did you know that geometry was invented by molecules? It's true! Until the first stars went supernova and littered all the elements across the cosmos, everything was simply spheres, from protons to stars. But then, under cooler planetary...

Learn what intermolecular forces are, the three most common types and the differences between them. An intermolecular force is simply an attractive force between neighbouring molecules. There are three common types of intermolecular...

This lesson will present the rules for writing the names and chemical formulae of elements and their allotropes.

Definitions included: chemical structure, ionic lattice, metallic lattice, molecule, covalent network, solitary atom,...

Learn the basics of alkanes and alkenes. After watching the covalent bonds video you should have sufficient knowledge to understand about how alkanes and alkenes are formed and the differences between them.

We've learned about VSEPR theory, and we know how to use it to predict molecular geometry for a variety of organic molecules. But in fact, there are situations where predictions made with VSEPR theory do not line up with experimental...

The video is a lecture on organic chemistry, introducing key concepts such as hydrocarbons, functional groups, homologous series, and isomerism. The speaker explains how organic molecules can be represented in different ways, using...
