Chemistry: Elements
Overview
The most powerful organizing concept in Chemistry is periodicity, the pattern of repeating chemical properties, which is represented by the periodic table. Two facets were known during the formation of the periodic table: different atomic masses such as the difference between lead and aluminum and combining capacities such as one atom of sodium with one atom of chlorine. Decades later additional relationships of ionization energy, boiling point, molar volumes were found. In addition to the general relationships of the periodic table several elements are scheduled for additional study. These elements are hydrogen and the hydrogen economy, calcium and its effect on human and soil equilibriums and carbon with an introduction to Organic Chemistry. Demonstrations will include colorimetry, soap making, and epoxy chemistry. Finally, every class member must have a project based on an element of the periodic table.
