This course aims to give fundamental concepts in chemistry to provide a strong basis for the follow up courses of the Chemistry minor. The atomic structure, notion of orbitals, bonding within molecules, and intermolecular interactions will be discussed, exploring the molecular reactivity but also the implications to the properties at the macroscale and materials science. Spectroscopic methods will be prresented, conceptually and experimentally, including the construction of a spectrometer and a short analytical chemistry lab.
