Etymology: "Superheavies" is the plural of "superheavy," a compound formed from the prefix "super-" (meaning above or beyond, here in the sense of exceeding a normal degree) and the adjective "heavy." The noun's sense in physics is quite different from the everyday meaning of "super" plus "heavy," which would suggest something merely very weighty. Here "superheavy" refers to chemical elements with very high atomic numbers, which are heavier than the ones found in the periodic table's natural series. The plural form simply names more than one such element, so the word is used when discussing the group collectively. Because the term is built transparently from two common English parts, its history is plain: it is a modern coinage assembled from existing words rather than a loan from another language.
