Trivial name

physical science Maturity 11-13 Next article →

In the world of chemistry, substances often carry two different types of names. There are formal, systematic names that follow strict rules of nomenclature. Then, there are trivial names, which are non-systematic or common names.

A trivial name is not recognized by formal systems like IUPAC inorganic or organic nomenclature. These names usually do not describe the essential molecular structure of a compound. Because they lack a strict structure, trivial names can sometimes be ambiguous. A name like "white metal" might mean different things in different industries or regions. Despite this, chemists still use many trivial names because they are traditional or more convenient than long, systematic ones.

To ensure global clarity, scientific documents, patents, and international treaties require unambiguous names. This need is met by systematic nomenclature. The International Union of Pure and Applied Chemistry, known as IUPAC, established a major system in 1950. Other organizations, such as the American Chemical Society and the World Health Organization, also develop naming systems. Some trivial names are so widely used that they are officially accepted by IUPAC as "retained names." In some cases, chemists even create semi-trivial names by adding a standard symbol to a trivial stem. This allows for a blend of traditional ease and modern precision.

Trivial names have many different origins, often rooted in history or the common language. Many names pre-date formal naming conventions and come from ancient practices like alchemy. Some names are based on the physical properties of a chemical. This includes its color, taste, smell, consistency, or crystal structure.

For example, the name bromine comes from a Greek word for "stink." The element iridium is named after "iris," the Latin word for "rainbow," because it forms many different colors. Other names are based on where a substance was found or the name of its discoverer. This connection to history helps us understand the journey of scientific discovery.

History shows how naming methods have evolved over centuries. During the Middle Ages, only nine elements were known: gold, silver, tin, mercury, copper, lead, iron, sulfur, and carbon.

Mercury was named after a Roman god, though its symbol comes from the Latin "hydrargyrum." Systematic nomenclature began to take shape after Louis-Bernard Guyton de Morveau called for a constant method of naming. This was popularized by Antoine Lavoisier in 1787 through his publication, "Méthode de nomenclature chimique." Lavoisier suggested naming elements after their properties. For 125 years, chemists used Greek and Latin roots to follow this idea, creating names like hydrogen, which means "water-producing."

Many elements are named after celestial bodies or mythological figures. Helium comes from the Greek "helios," meaning "Sun," because it was first detected in the Sun's spectrum. Other elements like selenium and tellurium are named after the Moon and Earth. Mythology provides names like titanium, named for the Titans, and uranium, named for a Roman god.

Some elements, like technetium and promethium, were named because their first samples were artificially synthesized. Others honor specific locations. Four elements—terbium, erbium, ytterbium, and yttrium—were named after the Swedish village of Ytterby, where their ores were found.

In organic and inorganic chemistry, trivial names often borrow from the kitchen or the senses. Early chemists used words like "butter," "oil," or "cream" to describe chemical consistency. For example, lead acetate was once called "sugar of lead."

Other names describe specific uses or origins. "Lime" comes from a root meaning "sticking," as it was used for construction mortar. In organic chemistry, lecithin is a trivial name for phosphatidylcholine because it was first isolated from egg yolks, which is "lékithos" in Greek. These names persist because the formal IUPAC equivalents are often too cumbersome for everyday use.

Today, the process for naming new elements is strictly regulated by IUPAC. When a new element is discovered, it is first given a systematic name based on its atomic number. For example, element 111 was temporarily called "unununium." Once the element is officially recognized, the discoverers can propose a permanent trivial name.

This new name then replaces the systematic one. This system allows scientists to honor people, places, or properties while maintaining a clear, organized record of the periodic table. It ensures that as science grows, our language for describing the universe remains both functional and meaningful.
