TED-ED: How atoms bond - George Zaidan and Charles Morton
Atoms can (and do) bond constantly; it's how they form molecules. Sometimes, in an atomic tug-of-war, one atom pulls electrons from another, forming an ionic bond. Atoms can also play nicely and share electrons in a covalent bond. From...

Conjugation & UV-Vis Spectroscopy: Crash Course Organic Chemistry
Carrots get their orange-y color from, you guessed it, an organic chemical. This chemical, called beta carotene, gets its pigment from its conjugated electron system. We’ve talked some already about conjugation, but in this episode of...

The Electron: Crash Course Chemistry
Hank brings us the story of the electron and describes how reality is a kind of music, discussing electron shells and orbitals, electron configurations, ionization and electron affinities, and how all these things can be understood via...

Electron Configuration
In this video Paul Andersen explains how to write out the electron configuration for atoms on the periodic table. More importantly he shows you why electrons arrange themselves in shells, subshells and orbitals by using Coulomb's law and...

3D Structure and Bonding - Crash Course Organic Chemistry
The organic molecules that make up life on Earth are more than just the 2-D structures we’ve been drawing so far. Molecules have 3-D shapes that help us understand what they can do. In this episode of Crash Course Organic Chemistry,...

Quantum Mechanical Model
In this video Paul Andersen explains how the quantum mechanical model of the atom refined the shell model. Uncertainty of the position of the electron as well as spin forces chemists to create an improved model. In this model the...

Using ROMAN NUMERALS to name Ionic Compounds w/ a Transition Metal in Chemistry!
Transition metals are elements in the d orbital. The reason these are unique is that they do not have 1 set charge they become when they become an ion like elements in the s and p orbital. Elements in the d orbital, or our transition...

Chemistry - Electron Configuration for Ions
Electron Configurations are essential to chemistry and they help us better understand and explain the position/location of electrons. Writing electron configurations can be daunting at first but once you see the pattern, you will be able...

Pauli's Exclusion Principle: The rule of electrons
Wolfgang Pauli's Exclusion Principle, developed in 1925, is a crucial concept in quantum mechanics. It states that two electrons in the same atom cannot have the same set of quantum numbers, which are the principal quantum number (𝑻n),...

Azimuthal Quantum Number: Shaping Electron Orbits
Characterised by the symbol 𝑙l, the azimuthal quantum number is a fundamental parameter in quantum mechanics that describes the angular momentum and form of an electron's orbital within an atom. The integer values it accepts range from 0...
