Subject - General Chemistry

The majority of main group elements and all elements of the other groups are metals. In the periodic table, the metallic character of the elements increases as you move from the upper right to the lower left. Typical main group metals are the alkali and alkaline-earth elements. The most reactive metals are the alkali metals (group 1). Typical members of the other groups include the lanthanides and actinides. Atypical metals include mercury, gallium, and indium, which do not crystallize in a typical metal structure.

Metals are elements with special properties. They conduct electricity, and are solid, ductile, and shiny.

Metals crystalize in metal lattices.
