We take a deep dive to understand how chemistry works at a fundamental level. All chemistry is about electrons. They are the primary drivers responsible for an atom’s behavior in chemical reactions, or more precisely the way...

“Static Electricity” demonstrates how rubbing some materials together makes static electricity.

Pupil outcome: I can describe how objects with a positive or negative charge attract or repel other charged objects. Key learning points: - Some objects can be charged by rubbing with certain materials. - Objects with a static electric...

Pupil outcome: I can describe what charges are and how they are transferred between some objects, giving them opposite charges. Key learning points: - Atoms contain positive and negative electric charges. - The particles in atoms with a...

Ready for action? Time to get your neurons firing with some action potential. If you thought resting potential was tough to understand, it seems like action potential is that much more difficult. However, thanks to Alie Astrocyte, we...

This video explains the formation of thunderstorms and how lightning and thunder are created. It describes how water vapor in the sky condenses into clouds, and when these clouds collide, electrical charges are produced. When these...

In this video, students will learn about atomic theory, atomic structure and how the atom is put together. This will include learning about the different subatomic particles, protons, neutrons and electrons, that make up the atom! This...

In this video, we'll be talking about how to determine the number of protons, neutrons, and electrons in an ion. We'll be using the periodic table to help us out, so don't miss it!

Ions are all around you and in many of the products and substances you encounter on a daily basis. Being able to determine the identity and difference between cations and anions is important for success in chemistry and physical science....

Metal excess defect due to excess cations occurs when extra positive ions (cations) are present in the crystal lattice, occupying interstitial sites to maintain electrical neutrality. To balance the excess positive charge, electrons are...

What is an atom? And what is it made of? In this video, I will be introducing you to the atom. We will also look at concepts like atomic mass, elements and isotopes.

We use a Van de Graaff generator to investigate static electricity. The generator is turned on and we see a spark move between the two domes. We then place a wig on the main dome and see the hair rise as the charge builds and the hairs...

Ever wondered how the motion of a conductor in a magnetic field generates voltage? We break it down with a real-world example of an airplane wing cruising through Earth's magnetic field. Don't worry; we keep it light and fun! Learn about...

Hyperconjugation plays a significant role in stabilizing carbocations, where adjacent alkyl groups donate electron density via sigma bonds to the positively charged carbon, spreading the charge and increasing stability.

The -M effect involves electron withdrawal through resonance. In nitrobenzene, the nitro group pulls electron density away from the benzene ring, decreasing electron density and making the ring less reactive in electrophilic substitution...

Resonance has far-reaching effects on molecular properties. It can equalize bond lengths, making double bonds longer and single bonds shorter than expected. It also stabilizes charged species, influencing acidity and basicity. For...

Electrophiles are electron-poor species, often possessing a positive charge or an empty orbital, making them highly reactive in seeking electron pairs from nucleophiles. Common examples include positively charged ions like
