Good morning/evening, everybody! Thank you for joining us last night.
We hope you discovered something interesting during the time we spent together on the Insomniac Net last night.

Periodically, we like to change our Question Topics.
For tonight's Net, we have shifted gears to explore a new topic -- The Periodic Table of Elements (get it?).
OK, OK, just relax!
No, you're not back in your high school science lab where some jerk poured a little hydrogen sulfide (H2S) on the radiator and they had to evacuate the school to clear out that smell of rotten eggs.
Instead, we'll be exploring some of the interesting stuff (we hope) about the 115 Elements that hang out on (or near) the Periodic Table.
OK, so how much do you know about the Elements you can take to the bank and make that "Ker-Chingk" sound -- the Precious Metals?
Please give us your best answers from any of the 3 (reuseable) answers of "A", "B", or "C" (if applicable!) for each question.
++ "It's Elemental, My Dear Dr. Watson -- #01: Precious Metals" ++
Question #1: Our 1st element has been the most prized precious metal throughout human history. It is usually found in relatively pure form. The Republican presidential candidate in 1964 looked to the Periodic Table of elements for the now iconic campaign graphic AuH2O which appeared on T-shirts, bumper stickers, coffee mugs, etc. What's the name of this element denoted by the chemical symbol "Au"?
A. Gold, or
B. Diamond, or
C. Uranium
The chemical symbol for Gold is Au, derived from the Latin word for gold, aurum.*
Barry Goldwater's 1964 presidential campaign looked to the Periodic Table of elements for the now iconic campaign graphic (Au = gold and H2O = water).

Also see: One of the less politically charged Goldwater campaign slogans, used mainly on bumper stickers, read simply "Au H2O 64" (combining the chemical symbols for gold and water).

Question #2: First found in ornaments and tombs dating as far back as 4000 BCE, and used for coins around 600 BCE, this 2nd precious metal, when mixed with the metal ("Au") in Question #1, makes that metal "whiter" (which some people prefer wearing, instead of its naturally occuring "yellow" color). What's the chemical symbol of this element?
A. Ag, or
B. Si, or
C. Sv
The precious metal/element Silver [Ag] symbol is derived from the Latin word for silver, argentum.*
By mixing silver with gold, the resulting alloy's color becomes paler and paler. White Gold Jewelry combines pure gold with other white metals, such as zinc, nickel, platinum and silver.
Question 3: This 3rd precious metal is listed just before Gold on the Periodic Table. In the 1500s, Spanish explorers in Columbia (SA) first discovered this shiny white element and named it "Platina del Pinto" which means "little silver of the Pinto River". Can you give us its name and chemical symbol of this element?
A. Platinum [Pt], or
B. Plutonium [Pu], or
C. Polonium [Po]
Platinum - the atomic number is 78 and the chemical symbol is Pt. The name derives from the Spanish platina for "silver".
Plutonium - the atomic number is 94 and the chemical symbol is Pu. The name derives from the planet Pluto, (the Roman god of the underworld). Plutonium was first synthesized in 1940
Polonium - the atomic number is 84 and the chemical symbol is Po. This radioactive metal was also known as radium-F. The name derives from "Poland", the native country of Marie Curie.
