Copernicium's atomic number is 113 and its symbol is Cn. Its known isotopes are extremely radioactive and have only been created in a laboratory. The most stable known isotope, copernicium-285, has a half-life of approximately 28 seconds. It is named after the astronomer Nicolaus Copernicus, and it was first created in 1996 by the GSI Helmholtz Centre for Heavy Ion Research near Darmstadt, Germany. Copernicium is calculated to have several properties that differ from its lighter homologs in group 12, and it may have more similarities to the noble gases such as radon. Predictions vary on whether solid copernicium would be a metal, semiconductor, or insulator. This display is contained within crystal clear Lucite acrylic.

Outstanding!
Format: Audiobook
Outstanding! Engrossing! I couldn't stop listening. It touched my soul on so many levels. I have a deeper level of respect for Ms. Cross, after this book. And having the audiobook spoken in her own voice, made it even more special. I will now have to purchase the hard copy.

T. Cross did it again!
Format: Kindle
She always conducted tv interviews and delivered her commentary in ways that uplifted and challenged. She writes in a way that captures the imagination and expresses solidarity with her people. She is undeniably human and relatable, and yet just as undeniably a unique and crucially needed voice. May T. Cross’ words long continue to grace us.

Great atlas for travel in British Columbia
Format: Spiral-bound
My spouse and I used this atlas during our recent travel within British Columbia. It is very useful with its broad details of data and the quality of the maps. There are two different scales of maps, depending on the purpose of the map - "Recreation" or "Landscape". The best scale is 1:300,000 on the landscape maps, which is certainly better than most road maps, especially when you consider the road network included in these landscape maps and the large size of the province. I recommend this atlas.

Get the most out of your travels
Format: Spiral-bound
This, like others in the same series, was a very helpful resource for a recent trip. I’ve never regretted buying these maps. Love the details and we have found many “roads less travelled” to explore with them.
