3 Periodic Table Periodic law: The chemical properties of elements are periodic functions of the atomic number Z Periods = rows Group = columns Metals Conduct heat, e-, shine, ductile, malleable. Can loose an e- easily and become cations; mostly solids Non-metals: right; brittle as solids, non conducting, can be gases, liq. or solids; tend to gain e- and become anions; combine among themselves to give covalent bonds (shared e-); combine with metals to give ionic bonds such as in ionic salts Semi-metals or metalloids: intermediate properties Elements in groups; similar chemical properties or families
