The Los Alamos National Laboratory publishes an annotated periodic table of elements as a resource for K-12 students. This accessible resource was originally created by Robert Husted back in 1992, but has since been updated and redesigned by other chemists at Los Alamos. The site's strength is its simplicity; students can click on each element to discover additional information. Each element's annotation follows a similar format, providing students with information about the element's history, sources, production, compounds, properties, uses, forms, isotopes, handling, hazards, or availability, as appropriate. In addition, students can find explanations of atomic numbers, atomic weights, and electron configuration on the How to Use page. The consistent format and clear language make this website a useful resource for students to explore during classroom projects or to study the periodic table at home.
