Promethium's atomic number is 61and its symbol is Pm. All of its isotopes are radioactive; it is extremely rare, with only about 500–600 grams naturally occurring in Earth's crust at any given time.

The discoverers proposed the name "promethium" (the spelling was subsequently changed), derived from Prometheus, the Titan in Greek mythology who stole fire from Mount Olympus and brought it down to humans, to symbolize "both the daring and the possible misuse of mankind's intellect". However, a sample of the metal was made only in 1963.

Practical applications exist only for chemical compounds of promethium-147, which are used in luminous paint, atomic batteries and thickness-measurement devices.

This display is contained within crystal clear Lucite acrylic.

Please note that this item might be classified as hazardous material in certain countries. We suggest checking local guidelines to ensure compliance before placing your order.

Safety

We get asked about the radioactivity and overall safety of the periodic tables/cubes from time to time. These are legitimate concerns and we wanted to address those concerns here. Although there are several elements in the cubes that are dangerous or toxic, the acrylic and glass ampules make the products safe to handle and store.

The average American is exposed to 0.034 mrem/hr from background radiation (300 mrem/year). In other words, a person will get three times the radiation from natural background radiation which includes the sun, food, radon, and the environment, than they will from holding a radioactive element in one of our Lucite Acrylic displays.

Care Instructions

Wash with mild soap or detergent and lukewarm water. Use a clean, soft cloth, or sponge. Rinse and blot dry with a damp cloth or chamois.

*Never use abrasive cleaners, household cleaners, window-cleaning fluids, scouring compounds, gritty cloths, or strong solvents such as alcohol, acetone, carbon tetrachloride, etc.*

To maintain the brilliant luster of acrylic, wax and occasionally with a quality grade of automobile paste wax (NOT A CLEANER WAX COMBINATION.) Apply a thin coat with a clean, cotton flannel cloth. Then wipe with a clean damp cloth. NEVER USE HOUSEHOLD SPRAY WAXES.
