The characteristics of bonds are specific to the atoms being held together. Bonds hold sets of atoms together in predictable proportions or even precise numbers in order to create a huge number of unique molecular substances with diverse physical and chemical properties. The strongest bonds—covalent bonds—form discrete molecules that interact with one another through weaker intermolecular forces. These activities will explore how molecules demonstrate the full range of bonds and intermolecular forces taught in middle school science courses, while being engaging and relatable for students.
