======================= SILVER ===========================
Name: Silver
Pronounced: SIL-ver
Symbol: Ag
Name origin: Anglo-Saxon: siolful, (silver); symbol from Latin: argentium.
Description: Silvery-ductile, and malleable metal
Discovered by: Known to the ancients.
Year: Unknown
Location: Unknown
Sources: Found in ores called argentite (AgS), light ruby silver (Ag3AsS3),
dark ruby silver(Ag3SbS3) and brittle silver.
Uses: Used in alloys for jewelry and in other compounds for photography. It is
also a good conductor, but expensive.

======================= SULFUR ===========================
Name: Sulfur
Pronounced: SUL-fer
Symbol: S
Name origin: Latin: sulphur (brimstone).
Description: Tasteless, odorless, pale yellow, brittle solid. Tenth most
abundant element in the universe.
Discovered by: Known to the ancients.
Year: Unknown
Location: Unknown
Sources: Found in pure form and in ores like cinnabar, galena, sphalerite and
stibnite. Pure form is obtained from undergound deposits by the Frasch process.
Uses: Used in matches, gunpowder, medicines, rubber and pesticides, dyes and
insecticides. Also for making sulfuric acid (H2SO4).
