EnvironmentalChemistry.com offers an extensive site on the element, Einsteinium, of the Periodic Table of Elements.

Set of tables describing many physical and chemical properties of the element vanadium.

In this module students explore how matter is classified, the history of atomic theory, subatomic particles, modern atomic theory, electron configuration, the periodic table and its trends, and spectroscopy.

This site offers physical data on the element Gadolinium. Also contains abundance and cost.

This site may focus on fun, rather than facts, but it will become a favorite of any Chemistry student. Here you will find scanned images of panels and/or pages of comic books, with references to the element you seek.

Beyond columns and rows, the periodic table groups elements according to families. Identify the families present on the table with this overview.

Students can use this chemistry tutorial to further their understanding of the families of elements on the Periodic Table of Elements.
