Symbol | Name | Fireworks Usage |
Al | Aluminum | Aluminum is used to produce silver and white flames and sparks. It is a common component of sparklers. |
Ba | Barium | Barium is used to create green colors in fireworks, and it can also help stabilize other volatile elements. |
Ca | Calcium | Calcium is used to deepen firework colors. Calcium salts produce orange fireworks. |
Cu | Copper | Copper compounds produce blue colors in fireworks. |
Fe | Iron | Iron is used to produce sparks. The heat of the metal determines the color of the sparks. |
Li | Lithium | Lithium is a metal that is used to impart a red color to fireworks. Lithium carbonate, in particular, is a common colorant. |
Mg | Magnesium | Magnesium burns a very bright white, so it is used to add white sparks or improve the overall brilliance of a firework. |
Na | Sodium | Sodium imparts a gold or yellow color to fireworks, however, the color is often so bright that is frequently masks other, less intense colors. |
P | Phosphorus | Phosphorus burns spontaneously in air and is also responsible for some glow in the dark effects. It may be a component of a firework's fuel. |
Sb | Antimony | Antimony is used to create firework glitter effects. |

How Many? A Dictionary of Units of Measurement © Russ Rowlett and the University of North Carolina at Chapel Hill
Article I, Section 8 of the U. S. Constitution gives Congress the power to "fix the standard of weights and measures" for the nation. The First Congress, meeting in 1789, took up the question of weights and measures, and had the metric system been available at that time it might have been adopted. What actually happened is that Thomas Jefferson, who was then serving as the first Secretary of State, submitted a report proposing a decimal-based system with a mixture of familiar and unfamiliar names for the units.
Jefferson's system actually resembles the metric system in many ways. Its biggest shortcoming is that Jefferson didn't hit on the idea of using prefixes to create names for multiples of units. Consequently, his system was burdened with a long list of names. For example, he divided his basic distance unit, the foot (it was slightly shorter than the traditional foot) into 10 inches. Each inch was divided into 10 lines, and each line into 10 points. For larger distances, 10 feet equalled a decade, 100 feet was a rood, 1000 feet a furlong, and there were 10 000 feet in a mile (making the Jeffersonian mile about twice as long as the traditional mile). His basic volume unit was the cubic foot, which he proposed to call a bushel (it was about 3/4 the size of a traditional bushel). The basic weight unit was the ounce, defined so that a bushel of water weighed 1000 ounces. (This is very similar to the metric system, in which a liter of water weighs 1000 grams).
Congress gave this plan serious consideration, but because it lacked independent support from other scientists it was easy to criticize. Ultimately, Congress took no action. This left Americans with a version of the traditional English weights and measures, including:
It is remarkable that Congress never established this traditional system, or any other system, as the mandatory system of weights and measures for the United States. In 1832, Congress directed the Treasury Department to standardize the measures used by customs officials at U.S. ports. The Department adopted a report describing the traditional system, and Congress allowed this report to stand without taking any formal action. This is the closest the U.S. has ever come to adopting a single system of measurement. Ironically, the U.S. missed two opportunities in 1832. Americans could have adopted the metric system, which was then at an uncertain point in its history; or they could have decided to align their measurements with the British Imperial measures established by Parliament in 1824 and thus created a possible alternative to the metric system in international commerce.

Scientists Announce Creation of Atomic
Element, the Heaviest Yet
By Rick Weiss
Washington Post Staff Writer
Tuesday, October 17, 2006; A03
Scientists in California and Russia announced yesterday that they have created the heaviest atomic element ever made, adding a new item to the universal menu of matter known as the periodic table and revealing fresh secrets about the nature of atoms, the fundamental units of physical stuff.
The new, radioactive element, which has not yet been formally named but is being referred to variously as ununoctium (Latin for "one-one-eight"), eka-radon (beneath radon on the periodic table) or simply element 118, did not linger long.
Indeed, as with most "super-heavy" elements -- which are not known to exist in nature but have been synthesized by slamming smaller atoms together -- the three atoms of ununoctium created in the latest experiments came and went in a literal flash.
But during their brief tenures of about nine ten-thousandths of a second each in a laboratory on Russia's Volga River, those three atoms revealed much about the laws that govern the behavior of matter, scientists said.
And while practical applications for such fleeting phenomena are difficult to envision, experts said they were confident some would appear -- especially if researchers can leverage the findings to make even larger atomic constructs that might have lifetimes of minutes, months or longer.
"One never knows what the application of the things you find may be," said Darleane Hoffman, a professor of chemistry at the University of California at Berkeley, tossing out the example of plutonium-239, the key fissile ingredient in atomic bombs, first created in 1941.
Physicists cautioned that the finding must be considered provisional for now. That is true of all experiments that have yet to be independently replicated, but especially so for the finding of element 118, whose discovery was first reported by a Berkeley team in 1999 and then retracted two years later when it became clear that the results were fraudulent.
The last new element to be confirmed was No. 111, roentgenium, discovered in 1994.
But scientists involved in the new find -- and others who reviewed the report, published in the October issue of the journal Physical Review C -- said they were virtually certain that what they saw in that millimoment was indeed a microhunk of ununoctium.
"I would say we're very confident," said team member Nancy Stoyer of the Lawrence Livermore National Laboratory in Livermore, Calif., estimating that the odds of the result being false were less than 1 in 10,000.
The team was led by Dawn Shaughnessy of Livermore and Yuri Oganessian of the Joint Institute for Nuclear Research in Dubna, Russia.
Every naturally occurring thing in the universe is made from a modest celestial palette of 92 elements, from hydrogen to uranium. Each element has an atomic number (from 1 to 92) representing the number of positively charged protons in that atom's core, or nucleus. Many variants, or isotopes, of each element also exist through the addition of varying numbers of uncharged neutrons to those nuclei.
For decades, scientists have been making new elements, heavier than any found in nature, in part to help them understand the basic forces that hold atoms together and keep them apart. They also want to know the biggest element that can be made. Theory predicts a finite limit.
The technique involves spraying a target made of one kind of atom with atomic buckshot of another kind and hoping that a few of the incoming nuclei will hit a few of the target atoms with enough force to overcome their mutually repulsive positive charges and merge into one giant nucleus, at least briefly. To accomplish that requires a combination of ultra-precise engineering and outlandish brute force.
In the latest experiments, which took more than 3,000 hours, the researchers fired about 40 billion billion atoms of calcium-48 -- a heavy, neutron-laden version of calcium -- at a target of californium-249, a highly radioactive synthetic element. Special sensors detected a total of three atoms of ununoctium flying off as a result of those painstaking efforts -- one in an experiment in 2002, and two in early 2005.
Each quickly threw off a pair of protons and a pair of neutrons to make element 116, then did so again to make element 114, and again to make element 112, which then split in two.
It is that trail of "daughters" that allows scientists to infer that a "mother" atom was there in the first place. But that kind of proof is tricky, said Walter Loveland, a chemistry professor at Oregon State University, because the super-heavy daughters are so poorly understood themselves.
Still, Loveland said he found the results "impressive and internally very self-consistent" and "a tremendous intellectual achievement."
One major question left unanswered by the experiment is whether there are super-heavy elements yet to be made that will be far more stable -- a predicted phenomenon that scientists have called "an island of stability."
An isotope of element 114, discovered by Livermore scientists, showed preliminary but now uncertain evidence of unusual longevity, on the order of 20 seconds. Some had predicted that ununoctium might stick around long enough for researchers to do some chemistry on it. The new work, while undermining that idea, offers new information that will help theoreticians revamp their predictions, which can then be tested by experimentalists.
"We're nibbling away at the shores of the island of stability," said Livermore's Ken Moody.

If you can remember the formula of the ion whose name ends with ate, you can usually work out the formulas of the other family members as follows:
Some anions can capture hydrogen ions. For example, carbonate (CO32- can capture an H+ to produce hydrogen carbonate HCO3- (often called bicarbonate). Each captured hydrogen neutralizes one minus charge on the anion.

You might be from the Northwest if you...
Know the state flower (Mildew). Feel guilty throwing aluminum cans or paper in the trash. Use the statement "sun break" and know what it means. Know more than 10 ways to order coffee. Know more people who own boats than air conditioners. Feel overdressed wearing a suit to a nice restaurant. Stand on a deserted corner in the rain waiting for the "WALK" signal. Consider that if it has no snow or has not recently erupted, it is not a real mountain. Can taste the difference between Starbucks, Seattle's Best, and Veneto's. Know the difference between Chinook, Coho, and Sockeye salmon. Know how to pronounce Sequim, Puyallup, Issaquah, Oregon, and Willamette. Consider swimming an indoor sport. In winter, go to work in the dark and come home in the dark, while only working eight-hour days. Never go camping without waterproof matches and a poncho. Are not fazed by "Today's forecast: showers followed by rain," and "Tomorrow's forecast: rain followed by showers." Cannot wait for a day with "showers and sun breaks." Have no concept of humidity without precipitation. Know that Boring is a town in Oregon and not just a state of mind. Can point to at least two volcanoes, even if you cannot see through the cloud cover. Notice "the mountain is out" when it is a pretty day and you can actually see it. Put on your shorts when the temperature gets above 50, but still wear your hiking boots and parka. Switch to your sandals when it gets about 60, but keep the socks on. Have actually used your mountain bike on a mountain. Think people who use umbrellas are either wimps or tourists. Knew immediately that the view out of Frasier's window was fake. Buy new sunglasses every year, because you can't find the old ones after such a long time. Measure distance in hours. Often switch from "heat" to "a/c" in the same day. Use a down comforter in the summer. Design your kid's Halloween costume to fit over a raincoat. Know all the important seasons: Almost Winter, Winter, Still Raining (Spring), Road Construction (Summer), Deer & Elk season (Fall). Actually understand these jokes and send them to all your friends in the northwest or those who used to live here!
