Tonight's Topic: "It's Elemental, My Dear Dr. Watson -- #02: Some Common Elements"
Answers = C - B - A
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.

KF7TBA+K7LWA's Friday Insomniac-Net BLOG (http://k7lwa-ins.blogspot.com/) |
Accordingly, we have shifted gears to explore a prior Question topic -- The Periodic Table of Elements (get it?).
Earlier this year, we posted questions about the Precious Elements: Gold, Silver, and Platinum.
For tonight's Net, especially for some of us common folk, we are asking you to identify three common elements that we find around us every day.
OK, OK, just relax!
No, you're not back in your high school science lab where some jerk tried to set your bagged lunch on fire with a Bunsen Burner.
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 these three Common Elements -- Calcium, Carbon, and Chlorine?
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 -- #02: Some Common Elements" ++
Question #1: Our 1st common element can only be found in nature as part of a compound. It is highly prized for its purifying, oxidizing, and anseptic properties, as well as its uses in manufacturing many of the products we use daily. Can you give us the name and chemical symbol of this common element?
A. Calcium [Ca], or
B. Carbon [C], or
C. Chlorine [Cl]
In nature it is found in the combined state only, chiefly with sodium as common salt (NaCl).
Chlorine is widely used in making many everyday products.
It is used for producing safe drinking water the world over. Even the smallest water supplies are now usually chlorinated.
It is also extensively used in the production of paper products, dyestuffs, textiles, petroleum products, medicines, antiseptics, insecticides, food, solvents, paints, plastics, and many other consumer products.
Most of the chlorine produced is used in the manufacture of chlorinated compounds for sanitation, pulp bleaching, disinfectants, and textile processing.
Some tree frogs contain a chlorine compound in their skin that is a very powerful pain killer. This chemical, when used in small doses, has no side effects; in large doses, however, it is fatal.

Question #2: Our next common element can be
found as some of the softest and hardest forms in and on earth. It can
be found in over 10 million compounds. It can be found in the sun, stars, comets, and even on
Mars! In fact, without it, the basis for life would be impossible! Can you give us the name and chemical symbol of this
common element?Chlorine is widely used in making many everyday products.

[CHLORINE -- Periodic Table of Elements: Los Alamos National Laboratory]
A. Calcium [Ca], or
B. Carbon [C], or
C. Chlorine [Cl]
Carbon, an element of
prehistoric discovery, is very widely distributed in nature. It is found
in abundance in the sun, stars, comets, and atmospheres of most
planets.
Natural diamonds are found in kimberlite of ancient volcanic "pipes," found in South Africa, Arkansas, and elsewhere.
Carbon is found free in nature in three allotropic forms: graphite, diamond, and fullerines. Ceraphite is one of the softest known materials while diamond is one of the hardest.
Carbon is unique among the elements in the vast number and variety of compounds it can form. There are close to ten million known carbon compounds, many thousands of which are vital to organic and life processes.
Without carbon, the basis for life would be impossible. The atmosphere of Mars contains 96.2% CO2. Some of the most important compounds of carbon are carbon dioxide (CO2), chloroform (CHCl3), carbon tetrachloride (CCl4), methane (CH4), ethylene (C2H4), acetylene (C2H2), benzene (C6H6), acetic acid (CH3COOH), and their derivatives.

Question
3:
This 3rd element is the fifth most common element found in the
earth's crust (3%). You can find it in leaves, teeth, shells, Portland
cement, and limestone caverns. Can you give us the name and
chemical symbol of this common element?Natural diamonds are found in kimberlite of ancient volcanic "pipes," found in South Africa, Arkansas, and elsewhere.

A. Calcium [Ca], or
B. Carbon [C], or
C. Chlorine [Cl]
Calcium, a metallic element, is fifth in abundance in the earth's
crust, of which it forms more than 3%. It is an essential constituent of
leaves, bones, teeth, and shells. Never found in nature uncombined, it
occurs abundantly as limestone, gypsum, and fluorite.
Its natural and prepared compounds are widely used.
When mixed with sand, it hardens mortar and plaster by taking up carbon dioxide from the air. Calcium from limestone is an important element in Portland cement.
