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.

Assignment #2

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) -1

• Cu(NO3)2 + NaOH → CuOH + Na(NO3)2

(aq) (s) (s) (aq) -1

• Cu(NO3)2 + NaS → CuS + Na(NO3)2

(aq) (s) (s) (aq) -1

• Cu(NO3)2 + NaPO4 → CuPO4 + Na(NO3)2

(aq) (s) (s) (aq) -1

• Cu(NO3)2 + NaSO4 → CuSO4 + Na(NO3)2

(aq) (aq) (aq) (aq)

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.
