In high school chemistry, we learn that Covalent bonds involve the sharing of one or more pairs of electrons between two atoms. We can represent these bonding pair of electrons in a diagram. The electrons are shown to be midway between the two atoms . For a homonuclear bond (two atoms are the same elements), this is approximately […]
Mastering VSEPR Shapes: Key Concepts for AP Chem In the month of October, many teachers often find themselves tackling Unit 2.7 of their course materials in AP Chemistry. This unit, which focuses on ‘VSEPR‘ (Valence Shell Electron Pair Repulsion) theory and ‘Bond Hybridization’ for AP Chem. Educators typically use this time to introduce their students […]
Teaching Titrations in Advanced Chemistry: A Visual and Interactive Approach Every year, chemistry students struggle with titrations—a topic packed with calculations, stoichiometry, and understanding molecular-level changes in acid-base reactions. Helping students grasp key aspects, like identifying equivalence points and understanding the major species present at different stages, can be a challenge for teachers. Using a […]
