The Gaming Table of the Elements
|
|
|
It's back to science class girls and boys! This list will attempt (over time and with your help) to catalog references to every element currently on the periodic table (and perhaps some that are not!). The idea came from a groovy site called "The Comic Book Periodic Table of the Elements" which can be found here: http://www.uky.edu/Projects/Chemcomics/For reference to the actual periodic table see the great WebElements™ periodic table which can be found here: http://www.webelements.com/For reference to a not so actual table please see this neat little page on Wikipedia called Fictional elements, isotopes and atomic particles which can be found here: http://en.wikipedia.org/wiki/Fictional_elementNow, let's hit the books... (ps: these are not in order. it's much too hard to come up with some of them so i wanted to get some easy ones right away. we'll fill in the gaps together later, neh?)

Name: hydrogen
Symbol: H
Atomic number: 1
Atomic weight: 1.00794 (7) g m r
Hydrogen is the lightest element. It is by far the most abundant element in the universe and makes up about about 90% of the universe by weight. Hydrogen as water (H2O) is absolutely essential to life and it is present in all organic compounds. Hydrogen gas was used in lighter-than-air balloons for transport but is far too dangerous because of the fire risk (Hindenburg). |

Name: helium
Symbol: He
Atomic number: 2
Atomic weight: 4.002602 (2) g r
Helium is one of the so-called noble gases. Helium gas is unreactive, colourless, and odourless. Helium is available in pressurised tanks.
Elemental helium is a colourless odourless monoatomic gas. Helium is the second most abundant element in the universe after hydrogen. a particles are doubly ionised helium atoms, He2+.
Helium is used in lighter than air balloons and while heavier than hydrogen, is far safer since helium does not burn. Speaking after breathing an atmosphere rich in helium results in a squeaky voice (don't try it!). |

Name: carbon
Symbol: C
Atomic number: 6
Atomic weight: 12.0107 (8) g r
Carbon is a Group 14 element. Carbon is distributed very widely in nature. It is found in abundance in the sun, stars, comets, and atmospheres of most planets. The atmosphere of Mars contains 96 % CO2.
Carbon is found free in nature in three allotropic forms: amorphous, graphite, and diamond. Graphite is one of the softest known materials while diamond is one of the hardest. Carbon, as microscopic diamonds, is found in some meteorites. Natural diamonds are found in ancient volcanic "pipes" such as found in South Africa. Diamonds are also recovered from the ocean floor off the Cape of Good Hope. |

Gold! [Average Rating:4.85 Unranked]
|
|

|
|
Name: gold
Symbol: Au
Atomic number: 79
Atomic weight: 196.96655 (2)
Gold is usually alloyed in jewellery to give it more strength, and the term carat describes the amount of gold present (24 carats is pure gold). It is estimated that all the gold in the world, so far refined, could be placed in a single cube 60 ft. on a side. It is metallic, with a yellow colour when in a mass, but when finely divided it may be black, ruby, or purple.
It is the most malleable and ductile metal; 1 ounce (28 g) of gold can be beaten out to 300 square feet. It is a good conductor of heat and electricity, and is unaffected by air and most reagents. |

Name: silver
Symbol: Ag
Atomic number: 47
Atomic weight: 107.8682 (2) g
Silver is somewhat rare and expensive, although not as expensive as gold. Slag dumps in Asia Minor and on islands in the Aegean Sea indicate that man learned to separate silver from lead as early as 3000 B.C. Pure silver has a brilliant white metallic lustre. It is a little harder than gold and is very ductile and malleable. Pure silver has the highest electrical and thermal conductivity of all metals, and possesses the lowest contact resistance. Silver iodide, AgI, is (or was?) used for causing clouds to produce rain. |

Name: palladium
Symbol: Pd
Atomic number: 46
Atomic weight: 106.42 (1) g
Palladium is a steel-white metal, does not tarnish in air, and is the least dense and lowest melting of the platinum group metals. When annealed, it is soft and ductile. Cold working increases its strength and hardness. It is used in some watch springs.
At room temperatures the metal has the unusual property of absorbing up to 900 times its own volume of hydrogen. Hydrogen readily diffuses through heated palladium and this provides a means of purifying the gas. |

Name: iron
Symbol: Fe
Atomic number: 26
Atomic weight: 55.845 (2)
Iron is a relatively abundant element in the universe. It is found in the sun and many types of stars in considerable quantity. Iron nuclei are very stable. Iron is a vital constituent of plant and animal life, and is the key component of haemoglobin. |

Name: sodium
Symbol: Na
Atomic number: 11
Atomic weight: 22.989770 (2)
Soap is generally a sodium salt of fatty acids. The importance of common salt to animal nutrition has been recognized since prehistoric times. The most common compound is sodium chloride, (table salt). |

is the best general argument, but a complex starting point.
There's a good brief piece with photos of an experiment at http://www.sas.org/tcs/weeklyIssues/2004-12-17/project1/inde...
The Wikipedia page provides a good overview of the controversy and links to details (including the links above): http://en.wikipedia.org/wiki/Hindenburg_disaster
