For this project, I will use the element Copper

Assignment #1 Atomic Symbol: Cu Atomic Number: 29 Atomic Mass: 63.546 Group: 11 Period: 4

Assignment #1 Physical State at Room Temperature: Solid Density at Room Temperature: 8.933 grams per cubic centimeter Color: Copper-red to brown. Tarnishes green, sometimes also blue, brown, red, or black Type of Metal: Transition metal Isotopes: 63Cu 65Cu Most common in nature: Copper metal does occur naturally, but by far the greatest source is in minerals. Copper is obtained from minerals by smelting, leaching and electrolysis. Summarize your research in three to five points.

Assignment #2 -1 Cu(NO3)2 + NaCl → CuCl + Na(NO3)2 (aq) (aq) (aq) (aq) A balanced chemical reaction with oxygen (metals) and name of product with physical states. Solubility reaction of nitrate with Cl, OH, S, PO4 and SO4 anions. -1 Cu(NO3)2 + NaCl → CuCl + Na(NO3)2 (aq) (aq) (aq) (aq) Cu(NO3)2 + NaOH → CuOH + Na(NO3)2 (aq) (s) (s) (aq) Cu(NO3)2 + NaS → CuS + Na(NO3)2 (aq) (s) (s) (aq) Cu(NO3)2 + NaPO4 → CuPO4 + Na(NO3)2 Cu(NO3)2 + NaSO4 → CuSO4 + Na(NO3)2 (aq) (aq) (aq) (aq)

Assignment #3 Molar Mass: 100/63.546 Cu = 1.574 100/16 O2 = 6.25 Limiting reagent using 100 g of copper and 100 g of oxygen, with number of moles of each. Molar Mass: 100/63.546 Cu = 1.574 100/16 O2 = 6.25 Limiting reagent: Cu

Assignment #4 Electronegativity: 1.54 Bond type with non-metals: ionic bonds Common isotopes: 63Cu, 65Cu Types of decay: 64Cu has a half-life of 12.701 ± 0.002 hours and decays by 17.86 (± 0.14)% by positron emission

Extra Facts: Although once made nearly entirely from copper, American pennies are now made from zinc that has been coated with copper. Due to its versatility and durability, copper is referred to as "man's eternal metal.” Because bacteria will not grow on it, copper has been used for centuries to line parts of ships so that barnacles and mussels do not stick to the boats. Foods rich in copper include oysters, beef, nuts, cocoa, black pepper, lobster, sunflower seeds, green olives, avocados, and wheat.
