Potassium's atomic number is 19 and its symbol is K. Pure potassium is shiny bluish-silver metal. It is about as soft as chilled butter. When potassium is exposed to air it quickly loses its luster and is covered in an oxide layer that is a greyish color. Potassium is very reactive. It catches on fire and explodes when it comes in contact with water shooting out flaming pieces of reacting potassium. In compound form, it is essential to balancing electrical charges in living cells. Potassium was first isolated by dissolving plant ashes in water to make potash. The resulting potash was high in potassium because plants have a significantly higher ratio of potassium to sodium. Modern-day potassium is mined from ancient lakes and seabeds that contain a high concentration of potassium salts and naturally created potash.  
The sample of potassium in this element cube display is encapsulated in an argon-filled glass ampule to prevent the potassium from oxidizing and preserve its shiny luster.

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.
