This document defines key chemistry concepts such as elements, compounds, and mixtures. It notes that elements are pure substances that cannot be broken down further, while compounds contain two or more elements chemically bonded together. The document also discusses trace elements essential for life like boron, copper, iodine, selenium, zinc, and iron, and some of their functions and dietary sources. It introduces the periodic table and explains that compounds have properties that may differ from their constituent elements.
