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.
