Al: This represents Aluminum, a lightweight and corrosion-resistant metal. Si: This is the symbol for Silicon, widely used in electronics and computer chips. P: This stands for Phosphorus, important in fertilizers and DNA. S: This s...
Unfortunately, the system fails for the elements in the first 3 periods (or rows; see below). For example, aluminum, in the column numbered 13, has only 3 s, p, and d orbital electrons. Nevertheless, the American Chemical Society has adopted the new IUPAC system. The horizontal rows of...

With the exception of boron,group IIIA elements are also fairly reactive metals.Aluminum appears to be inert toward reaction with air,but this behavior stems from(来源于,起源于) the fact that the metal forms a thin, invisible film of aluminum oxide on the surface, which protects the bulk of...
About 75 percent of the mass of the universe consists of hydrogen, making it the most abundant element. It is a colorless and odorless gas that makes up nuclear matter. The second most abundant is helium, which accounts for about 25 percent of the mass. Other elements include oxygen, iron...
