So so tired...........
Element of the day (day 89)
#88) Ra- Radium-] radioactive
Discovered in 1898 by Marie and Pierre Currie, France.
Radioactive as well as chemically active, reacting with air, water, and acids. Used to treat cancer and in making luminous paints and glow-in-the-dark watch dials, but for the most part it is no longer used for these purposes.
A decay product of uranium, so it is found in small amounts in all uranium-bearing rocks. It was chiefly obtained as a by-product of uranium processing. It is seldom collected anymore.
