CHEM 6A Lecture #2 (10-02-08) - The radioactive isotope 14C has how many electrons, neutrons, and protons? - Metals: metallic luster (or shine), good conductor of heat/electricity, malleable (may be hammered into a sheet) and ductile (may be drawn into a wire) - Non-metals: dull color, brittle, not a good conductor of heat/electricity - LHS: metals except hydrogen, zig-zag: B, Si, Ge, Sb, Po, As, Te (semi- metal/metalloids), RHS: non-metallic - Lighter elements are gases (N2, O2, F2) and the heaviest elements are solids (Bi Te, I2) - Group I Alkali Metals : combine w/water to give alkaline solutions, relatively soft metals that may be cut with a knife, malleable and ductile (i.e. sodium wire) and chemistry is dominated by compounds that feature M+ ions: M -> M+ + e- (i.e. NaCl) - Group II Alkaline Earth Metals : “Earth” refers to substances that are insoluble in water and stable to heat – the oxides of these elements, are harder than alkali metals, less reactive than alkali metals and chemistry is dominated by compounds
