Metals

Question 1

Iron Ore

Answer 1

Refined by reduction in blast furnace, molten iron in blast furnace called pig iron.

Question 2

Three Ways of Making Steel

Answer 2

Basic Oxygen Furnace
Open-Hearth Furnace
Electric Arc Furnace

Question 3

Alloys

Answer 3

Mixture of two or more metals.
Melting point of alloys are LOWER than its components’ melting points
Hardness increases in alloys
Size of crystalline particles determine physical properties of alloy (cooled slowly=larger crystals)

Question 4

Common Alloys

Answer 4

Brass: copper and zinc
Bronze: copper and tin
Steel: controlled amounts of carbon, manganese, sulfur, phosphorus, and silicon, alloyed with nickel and the chromium
Sterling silver: alloyed with copper

Question 5

Metalloids

Answer 5

Form ionic or covalent bonds

Semiconductors

Question 6

Answer 6

Metallic Luster
Conduct heat and electricity 
Malleable (can form sheets)
Ductile (can form wires)
Silvery (most)
Insoluble w/o chemical change/in typical solvents
