The thought of packing up and leaving my children's home is killing my spirit and destroying my heart even more than it already is--totally overwhelming...
Element of the day (day 47)
#44) Ru-Ruthenium -] metal
Discovered in 1844 by Karl Klaus, Russia.
A lustrous, silvery-white metal. Very hard and brittle, so much so that it cannot be worked when pure. Very stable, unaffected by air, water, and acids. When alloyed with platinum or palladium, ruthenium hardens those metals to a high degree. Also alloyed with titanium to greatly improve that metal's resistance to corrosion. A very useful chemical catalyst.
One of the platinum group elements. It is produced as a by-product from copper-nickel-platinum mining in Russia, Canada and South Africa.
