Updated and redesigned to current IUPAC standards.

Designed to maximize visibility and minimize confusion, this concise chart deals with essentials - presenting only the atomic symbol, atomic mass (based on carbon 12), atomic number, name of the element and selected oxidation states.

Printed on tear and water-resistant synthetic stock, the atomic symbols are color-coded to designate the naturally occurring physical state of each element - solids black, gases white, liquids blue. Synthetic elements are shown in gray. Atomic numbers appear red, all other type is black. Additional color-coding is used to designate s-block, d-block, f-block, and p-block elements.

Mounted with removable black Snap-Grip® trim on top and bottom that includes removable / repositionable eyelets ready for hanging.
