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.
Assignment #2

Assignment #3
Limiting reagent using 100 g of copper and 100 g of oxygen, with number of moles of each.
Molar Mass:100/63.546 Cu = 1.574100/16 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.
