The number of electrons in an atom is usually the same as the number of protons, and thus most atoms have a neutral charge.In certain situations, however, the atom may lose or gain one or more electrons and acquire a net charge, becoming an ion.The electrons are not "lost" when an atom becomes an ion: they simply go elsewhere.Aluminum Al , for instance, has an atomic number of 13, which tells us that an aluminum atom will have 13 protons.Given the fact that every proton has a positive charge, and that most atoms tend to be neutral in charge, this means that there are usually 13 electrons, with a negative charge, present in an atom of aluminum.Aluminum may, however, form an ion by losing three electrons.How do we know this? The rest are all solids.The noble gases are monatomic, meaning that they exist purely as single atoms.So too are the "noble metals," such as gold, silver, and platinum.On the other hand, a number of other elements are described as diatomic, meaning that two atoms join to form a molecule.As noted above, the periodic table includes the element symbol or chemical symbol — a one-or two-letter abbreviation for the name of the element.Many of these are simple one-letter designations: O for oxygen, or C for carbon.Others are two-letter abbreviations, such as Ne for neon or Si for silicon.Note that the first letter is always capitalized, and the second is always lowercase.In many cases, the two-letter symbols indicate the first and second letters of the element's name, but this is far from universal.Cadmium, for example, is abbreviated Cd, while platinum is Pt.In other cases, the symbol seems to have nothing to do with the element name as it is normally used: for instance, Au for gold or Fe for iron.Many of the one-letter symbols indicate elements discovered early in history.For instance, carbon is represented by C, and later "C" elements took two-letter designations: Ce for cerium, Cr for chromium, and so on.But many of those elements with apparently strange symbols were among the first discovered, and this is precisely why the symbols make little sense to a person who does not recognize the historical origins of the name.For many years, Latin was the language of communication between scientists from different nations; hence the use of Latin names such as aurum "shining dawn" for gold, or ferrum, the Latin word for iron.Likewise, lead Pb and sodium Na are designated by their Latin names, plumbum and natrium, respectively.Some chemical elements are named for Greek or German words describing properties of the element — for example, bromine Br , which comes from a Greek word meaning "stench.The names of several elements with high atomic numbers reflect the places where they were originally discovered or created: francium, germanium, americium, californium.Americium and californium, with atomic numbers of 95 and 98 respectively, are among those elements that do not occur naturally, but were created artificially.The same is true of several elements named after scientists — among them einsteinium, after Albert Einstein , and nobelium after Alfred Nobel , the Swedish inventor of dynamite who established the Nobel Prize.The first two elements on the periodic table, hydrogen and helium, represent References Feliway: Glossary of Cat Behavior ASPCA: Cats and Babies.
