This video provides a brief overview of the history and function of electricity, debunking the misconception that Benjamin Franklin invented it. It explains how electricity has always existed in nature and how figures like Franklin and...

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...

Writing formulas for ionic compounds is all about canceling out the charges! An ionic compound is formed between a cation and an anion, or a positive and negative charge so the goal is to always get the charges to add up to zero! In this...

Tetrahedron formation is a crucial aspect of the chemical bonding and molecular geometry of Group 4 elements like carbon, silicon, germanium, tin, and lead. The tetrahedral shape is formed by the arrangement of four substituents around...

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....

Weird History Food is sending you a SPAM alert. No, not those annoying emails you get from Planet Fitness, but the delicious ham in a can. SPAM has a longer history than you would expect, but probably a little longer than a can of SPAM's...

Learn about the early life of Zheng Yi Sao, a woman who defied societal norms to become a powerful pirate. She leveraged her intelligence to rise to power, eventually marrying the pirate Zheng Yi, with whom she formed a formidable...

Explore the dynamics of RC circuits in this informative lesson. Unveil the charge and current as functions of time within an RC circuit. We dive into the Kirchhoff’s Loop Rule and differential equations to derive key insights. Witness...

Good morning! In this episode of Flipping Physics, we explore the dynamic world of RC circuits—combining resistors and capacitors in electric circuits. Discover how electric potential differences, current, and charge on capacitor plates...

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.

Bohr's model of the atom says that an electron's energy is set by its orbit around the nucleus. Bohr said that electrons have specific, quantised levels of energy, and that the size of the orbit affects the energy...

Bohr's atomic model postulates that the radius of an electron's orbit around the nucleus is determined by the concept that electrons travel in quantised orbits with distinct and well-defined radii. According to the model, the angular...

Formal Charge Made Simple: A Guide to Molecular Stability Formal charge is a bookkeeping tool used to estimate the charge distribution within a molecule. It is calculated by comparing the number of valence electrons in an atom's free...

In this topic, we explore how to draw and interpret the Lewis structures of carbon dioxide (CO₂) and nitrogen dioxide (NO₂), two important molecules in chemistry. CO₂ features a linear structure with double bonds between carbon and...

Lewis structures are diagrams that represent the bonding between atoms in a molecule and the lone pairs of electrons that may exist. These structures are crucial in understanding how atoms share or transfer electrons to form stable...

Lattice energy depends on ion size, charge, and the arrangement of ions in the crystal lattice. Smaller, highly charged ions increase lattice energy.
