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…
