Other Elements of Interest Beyond the first twenty elements of the periodic table there are many others that are particularly interesting.
Today's Starter Quote Don’t go around saying the world owes you a living. The world owes you nothing. It was here first. – Mark Twain
Iron Symbol Fe Origin : latin, Ferrum Uses: Major component of steel
Nickel Symbol: Ni Number of protons or electrons: 28 Uses: Nickels (but it's actually mostly iron now), heating coils and Ni-Cd batteries
Symbol: Cu Number of neutrons: 35 Uses: Pennies (though less than 5%), wiring, drain cleaner and piping for water Copper
Zinc Symbol: Zn 35 Neutrons Uses: inside of pennies, plating for screws and nails (galvanized)
Bromine Symbol: Br Atomic Number: 35 Uses: one of two elements that is a liquid; salts are used in hot tubs
Silver Symbol: Ag Origin: Argentum (money) Uses: Jewelry, currency/coins, anti-microbial cloths
Iodine Symbol: I Atomic Mass: 127 amu Uses: formerly a disinfectant, prevents goiter
Gold Symbol: Au Origin: Aurum (latin) Uses: currency, jewelry, plating for very expensive wiring
Mercury Symbol: Hg Origin: Latin (hydrogyrum – shiny water) Uses: liquid, old thermometers, old thermostats, lights, batteries
Lead Symbol: Pb Origin: latin (plumbum) Uses: very old piping, but it's toxic to humans (lead poisoning)
Uranium Symbol: U Uses: Fuel rods for nuclear power production, weaponry, insulating for old telephone wiring
