This unit begins by asking students how we know the identity of stuff, probing students to consider what makes different items different and unique. This unit uses various metals to investigate these questions in an introductory unit for first-year (sophomore) chemistry. The unit discusses the history of the atom, the components of the atom, the electron, and begins to discuss metallic bonding. This unit connects chemical concepts of stability and uniqueness to further explore economic concepts.
