Document Summary

2. 6 elements: a first look at the periodic table. 8 a groups (2 on left, 6 on right) contain the main-group elements. The 10 b groups, located b/w groups 2a(2) and 3a(13), contain the transition elements. 2 horizontal series of inner transition elements, the lanthanides and the actinides, fit between the elements in group 3b(3) and group 4b(4) and are placed below the main body of the table. Metals: lie in the large lower-left portion of the table. Can be tooled in sheets (malleable) and wires (ductile) Nonmetal: lie in the small upper-right portion of the table. Generally gases or dull, brittle solids at room temp. Metalloids: aka semimetals, lie along the staircase line. Have properties b/w those of metals and nonmetals.
