This episode discusses mass percent, a way to express the mass contribution of each element in a compound. It defines it with the formula: (mass of the element / total mass of the compound) x 100%. T…

This episode discusses molar mass, defining it as the mass of one mole of a substance in grams. It explain that it's numerically equal to an element's atomic mass, making the periodic table a direct …

This episode introduces organic nomenclature, a new system for naming hydrocarbons like alkanes and alkenes. Alkanes (single bonds) are named using a prefix for the carbon chain length followed by -a…

This episode explains acid naming, which combines rules from both ionic and covalent nomenclature. Acids are split into two types: binary acids and oxyacids. Binary acids (hydrogen + a nonmetal) are …

This episode explains the systematic rules for naming binary covalent compounds. Unlike ionic compounds that are named by balancing charges, covalent compounds are named by counting atoms and using n…

This episode explores the properties of light and its connection to chemistry. It explains that light is a form of electromagnetic radiation that acts as both a wave and a particle (photon). Key rela…

This episode explores how electron shielding and effective nuclear charge are crucial for understanding atomic behavior and periodic trends. It explains that electron shielding occurs when inner-shel…

This episode explains significant figures, which are the meaningful digits in a number that reflect a measurement's precision. It outlines rules for identifying them: non-zero digits are always signi…

This episode explains intermolecular forces (IMFs), the attractions between molecules that determine physical properties. The three main types are: London dispersion forces (present in all molecules …

This episode explains VSEPR (Valence Shell Electron Pair Repulsion) theory, a method for predicting the three-dimensional shapes of molecules. The core principle is that electron pairs around a centr…

This episode explains formal charge, a tool for evaluating Lewis structures. It defines formal charge with the formula FC = V - N - B/2 and outline key rules for its use, such as minimizing charges a…

This episode explains resonance, where a molecule cannot be accurately represented by a single Lewis structure. Resonance occurs when multiple valid Lewis structures can be drawn by moving only elect…

This episode discusses three exceptions to the octet rule: incomplete octets (e.g., boron in BF3), odd electron species with an unpaired electron (e.g., NO), and expanded octets (e.g., sulfur in SF6)…

This episode classifies compounds into three types based on their chemical bonds: ionic, covalent, and metallic. Ionic compounds, formed by electron transfer, are brittle with high melting points and…

This episode provides a six-step guide to drawing Lewis structures, diagrams that show how valence electrons are arranged in molecules. It explains how to count electrons, identify a central atom, an…

This episode explains UV-Vis spectroscopy, an analytical technique that measures how much ultraviolet and visible light a substance absorbs. It describe how the instrument works, its main components,…

This episode explains that an atom's or molecule's magnetic behavior, either diamagnetism or paramagnetism, is determined by its electron configuration. Diamagnetism is present in all substances with…

This episode explains that quantum numbers are a set of four values that serve as a unique address for every electron. The Pauli exclusion principle states that no two electrons can have the same fou…

This episode defines electron configuration as the arrangement of electrons in an atom's orbitals. It explain two notation methods: standard notation (e.g., 1s2) and orbital box notation, and outline…

Think of an electron's path around an atom. If you're imagining a planet orbiting the sun, think again! In this episode, we're diving into the strange and fascinating world of atomic orbitals. We'll …
