This document discusses properties of elements and compounds. It begins by explaining atomic mass, metallic radius, and ionic radius. It then discusses ionization energy, electronegativity, and electron affinity as factors that influence chemical bonding properties. Various groups on the periodic table are described including their common oxidation states and bonds formed. Transition metals are also briefly mentioned.
