Water molecules

That webpage with the discussion of water molecules was interesting. it was very simple to understand the basic concept of a water molecule because of the way the page had been organized. i enjoyed seeing the various patterns water molecules make, and it made me think about how nature is all patterns, and how intelligent all the atoms in nature, or whatever designed the atoms, are. i liked seeing how the one molecule of water surrounded by four other water molecules created a pattern, which was easy to see because the molecules were color-coded to show a clear distinction between Hydrogen and Oxygen.

Cu

Copper is my transitional metal for the week. I chose this because I have always liked the metal when used in jewelry, in fact my friend in tucson uses copper pennies and puts them on the train tracks and makes earrings from them.
-atomic number is 29. It is a ductile metal with very high thermal and electrical conductivity.
-copper metal can be used as an anti-germ surface that can add to the anti-bacterial and antimicrobial features of buildings such as hospitals.
-In sufficient amounts, copper salts can be poisonous
-the 2+ copper ion at lower concentrations is an essential trace nutrient to all higher plant and animal life.
-In animals, including humans, it is found widely in tissues, mostly in liver, muscle, and bone.
-It functions as a co-factor in various enzymes and in copper-based pigments.
