Atom economy

I went on the site for atom economy and to me it seemed that alot of the links it sent you to were sites with the key words in them, but most of the sites were unrelated to atom economy. they were sites that were selling me products.
I did however find the site on green innovation much more to my liking. Heres a quote from it that I liked.
"fundamentally things that need to be changed will be changed- without threatening the things that need to be sustained."

Green chemistry as a social movement

I think that as we all realize the importance of the health of our planet, green chemistry will make more and more sense to everyone. It is a social movement because we are socially responsible to clean up our messes. That is certainly a lesson that I am instilling in my children, as individuals and as humans on this planet. Green chemistry helps industries have guidelines to follow that will in the future leave us with only self contained products. The idea that we use up all atoms so there are no by products left over, sounds like a tough act to follow, but certainly a wonderful goal. If we look at our lives often we try to this with our food. When I buy groceries I am conscious to get just the things I will use in the week being sure to get things that spoil quickly in small quantities and if for some reason I over buy, i make bannana bread, or pumpkin muffins. Trying to use every atom....

Catalyst of the week

Palladium
Atomic number 46. Palladium is a rare and lustrous silvery white metal that was discovered in 1803 by William Wollaston, who named it after the asteroid Pallas.
Over half the supply of palladium and it's sister metal platinum goes into catalytic converters,which convert up to 90% of harmful gases from auto exhaust(hydrocarbons,carbon monoxide, and nitrogen oxide) into less harmful substances(nitrogen, carbon dioxide, and water vapor)

Water concepts

I loved this site. It was so enlightening to see everything in 3d. I loved how it asked questions and then shortly after gave the answer with a picture. I was able to see how the water molecule reacts under different temperature conditions. this is my kind of science.

Transition metal of the week

Zinc is similar to magnesium because it's ion is of similar size and it's only common oxidation state is 2. Zinc is the 24th most abundant elements in the earths crust and has five stable isotopes. The element was probably named by the alchemist Paracelsus after the German word Zinke. Corrosion- resistant zinc plating of steel is the major application of zinc.

my review of links on atomic structures.

I am so excited I finally get electron configuration....! It was after taking a look at the first link atomic properties ,that it all started to sink in. I took a look at covalent bonding, that looks fascinating too, symbiotic bonding, what a way to keep the elements balanced. I am eager to continue learning and using these sights as compliments to the class.

Element of the week:Titanium

Titanium.....
A metal element,that's recognized for its high strength to weight ratio.
Commercial grades of titanium have the same strength as low grade steel alloys but are 45% lighter.It's also corrosion resistant(including, sea water,aqua regia, and chlorine)
Titanium can be alloyed with iron,aluminum, among other elements to produce strong lightweight alloys for aero space. It's electron configuration is (Ar) 4s(2)3d(2)

Periodic tables...

I took a look at the spiral periodic table, that was confusing, then I tried the quiz ,but that was too difficult to understand, then I finally found the game...I love the game because for a novice like me I can feel like I actually retained some knowledge from high school. I also found it useful because as I am playing the game I am learning.

my quiz results

I found the quiz a bit disconcerting, having very little memory of chemistry. On question one I thought dissolving sugar was a chemical process, and in question two I thought milk was pure.
