Chemists are usually asked to invent a solution, but without considering hazardous by-products. Green chemists now are doing both with success, but will it take regulations to enforce the approach broadly?
A Mad Science Room activity from Crazy Aunt Lindsey
Many of the most profound scientific questions—and some of humanity's most urgent problems—pertain to the science of atoms and molecules
Whether gas, liquid or solid; radioactive or stable; reactive or inert; toxic or in your vitamin pill, the 118 building blocks each has its own chemically idiosyncratic characteristics--and certain commonalities. See what makes your favorite element unique on this interactive periodic table
Credit: IStockphoto I knew I wasn't like the other kids. Oh sure, I collected baseball cards and model airplanes, but not with the passion that I saved for my real obsession—collecting each and every element of the periodic table.This was just part of my chemical romance, which also involved (but was not limited to): watching phenolphthalein solution in test tubes change color, launching sodium carbonate/acetic acid (vinegar)–powered rockets, generating the sulfurous odor of rotten eggs and making a smoke bomb that accidentally detonated in the basement, and eventually graduating to electrolysis and various combustibles that fortunately resulted only in singed eyebrows, but no loss of digits or eyesight.Outside of explosives, however, lay the Holy Grail—a complete set of the fundamental building blocks of the universe.
