General Chemistry/Periodic Table


This table is a detailed periodic table that does not fit on most computer screens. However, in print with a small font, or in landscape mode, this table can be printed onto a single normal-sized paper (A4 or 8½ x 11"). For a printable version that uses less colored ink (and works without color), see this.

Elements 103-118 don't have the same atomic [weight] represented everywhere.
Elements with [atomic weights in brackets] are rounded from their actual atomic weights.
Metals, metalloids, and nonmetals have no one definition.
