Technetium Element Cube

    Technetium's atomic number is 43 and its symbol is Tc. It is a silvery-gray transition metal, tarnishes slowly in moist air, and is the lightest radioactive element. It dissolves in nitric acid, aqua regia (nitro-hydrochloric acid) and concentrated sulfuric acid, but is not soluble in any strength of hydrochloric acid.

    Its name comes from the Greek technetos, artificial. This is due to the element not appearing in nature. Therefore, it can only be produced in a laboratory. Technetium is a remarkable corrosion inhibitor for steel, and is an excellent superconductor.

    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.

    Proudly made in the U.S.A.
