Chemistry Week Three Assignments

Transitional Metal, Copper (Cu)

Copper has an atomic number of 29, it has 29 Protons and 29 Electrons. It has 35 Neutrons, and an atomic mass of 63.546. Its Crystal Structure is Cubic.
Copper has one electron at the 4th energy level, meaning, it occupies 4 energy levels.
It conducts electricity and is used often in Jewelry, plumbing and coins (although the copper penny has now been replaced with a copper nickel alloy because the worth of the copper exceeded the worth of the penny.)
Copper is found in humans in the Liver, Bone and muscle. It is a necessary dietary nutrient.
Pure copper is soft, alloys are used to make copper use functional.
Copper oxidizes with air and turns a darker color, but normally it is red or orange.

The article Neptune's Medicine Chest makes me feel conflicted. On the one hand it is important to and so many people are depending on finding cures for cancer, etc. The ocean is a vast resource that is largely unexplored. On the other hand, the article makes plain that this is a capitalistic venture, that cures are patented. That it is only within large (quasi governmental) institutions like universities where research is being done. Once again, there seems to be no concern for environment... environment leading to disease, environment that may be destroyed through misuse, environment having its own integrity to respect. It made me sad to think of these well funded scientists drinking margaritas and not considering the angle their work assumes.

What an amazing link, Advancing Green Chemistry! I feel like I could, and will spend some serious time on this site. I read an article about Phalates and an article about stain protectors found in increasing amounts in the blood stream. There certainly are people doing good in the world, people who are interested in honestly looking at what we are doing and coming at the issues of today, lie cancer, from a different angle that could result in future preventative results.
