Unit 5: Intermolecular Forces

Learning Objectives for Unit 5 is located here.

Form follows function is seen in many worlds including both science and art, broadly. How atoms are arranged and their individual structure is arguably one of the most important - yet simple - concepts that many glance over. Do not underestimate the importance of electrostatic attractions and repulsions to chemistry. To be discussed: anatomy of an atom, history of the atom, Bohr's model of the hydrogen atom, representation of orbitals, electron configurations and periodic table, effective nuclear charge, atomic and ionic size, ionization energy, electron affinity, ionic and covalent bonding, bond polarity and electronegativity, drawing Lewis structures and resonance structures, exceptions to octet rule, VSEPR model, molecular polarity, and hybridization.
