Elements Named After Scientists, Countries, and Mythology

A Tour Through Human History in 118 Names

Naming an element is one of the highest honors in science — and one of the most political. The International Union of Pure and Applied Chemistry (IUPAC) enforces strict rules: new elements can be named after a mythological concept, a mineral, a place, a property of the element, or a scientist. What IUPAC forbids is naming elements after living politicians or commercial brands. The result is a table that reads like a tour through human civilization — its gods, its explorers, its greatest scientific minds, and its most consequential places.

Fifteen Elements Named After Scientists

The most prestigious category. Einsteinium (Es, 99) honors Albert Einstein, though the element was discovered in the debris of the first hydrogen bomb test — a context Einstein would have found deeply troubling. Curium (Cm, 96) commemorates Marie and Pierre Curie, the husband-and-wife team who pioneered radioactivity research and paid for it with their health. Marie Curie's laboratory notebooks are still so radioactive they must be stored in lead-lined boxes.

Mendelevium (Md, 101) honors the man who started it all — Dmitri Mendeleev, creator of the periodic table. Fermium (Fm, 100) is named for Enrico Fermi, who built the first nuclear reactor under the bleachers of a squash court at the University of Chicago in 1942. Nobelium (No, 102) commemorates Alfred Nobel, inventor of dynamite and founder of the Nobel Prizes.

Among more recent additions, flerovium (Fl, 114) honors Georgy Flyorov, who wrote a famous letter to Stalin in 1942 pointing out that Allied physicists had stopped publishing about nuclear fission — correctly deducing that they were building a bomb. Flyorov later founded the Russian laboratory where several superheavy elements were synthesized.

Oganesson (Og, 118) honors Yuri Oganessian, the Armenian-born nuclear physicist who led the creation of multiple superheavy elements. He's one of only two people to have an element named after them during their lifetime. The other was Glenn Seaborg, who got seaborgium (Sg, 106) — and reportedly joked that he was the only person in history whose address could be written entirely in chemical symbols (Sg, Lr, Bk, Cf, Am).

Other scientists honored include Bohrium (Bh, 107, Niels Bohr), Meitnerium (Mt, 109, Lise Meitner — who was denied a Nobel Prize despite co-discovering nuclear fission), Rutherfordium (Rf, 104, Ernest Rutherford), Lawrencium (Lr, 103, Ernest Lawrence), Roentgenium (Rg, 111, Wilhelm Rontgen), Copernicium (Cn, 112, Nicolaus Copernicus), and Tennessine — wait, that one's a place.

Places That Became Elements

Geography dominates element names, and one tiny Swedish village holds the all-time record. Yttrium (Y, 39), ytterbium (Yb, 70), terbium (Tb, 65), and erbium (Er, 68) are all named after Ytterby, a small mining village near Stockholm. A single quarry there yielded four new elements in the 18th and 19th centuries — a density of discovery unmatched anywhere on Earth. The quarry is now a historical landmark.

The Americas contributed a cluster from the University of California, Berkeley: californium (Cf, 98), berkelium (Bk, 97), and americium (Am, 95). Americium is in virtually every smoke detector — it emits alpha particles that ionize air between two plates, and when smoke disrupts the current, the alarm triggers. There's a tiny speck of a transuranic element protecting you while you sleep.

European geography fills the table. Gallium comes from Gallia (France), germanium from Germany, polonium from Poland (named by Marie Curie to draw attention to her homeland's struggle for independence), francium from France, scandium from Scandinavia, and hafnium from Hafnia, the Latin name for Copenhagen. Nihonium (Nh, 113) represents Japan ("Nihon"), the first element named in East Asia. Moscovium (Mc, 115) honors Moscow and the Moscow Oblast.

Even continents get credit: europium (Eu, 63) for Europe, and americium (Am, 95) for the Americas.

Gods and Ancient Myths

Mythology contributes some of the table's most evocative names. Thorium comes from Thor, the Norse god of thunder — fitting for an element that could power the next generation of nuclear reactors. Titanium references the Titans of Greek mythology, primordial gods of immense strength. The name captures the metal's character — it's as strong as steel at 45% less weight.

Promethium takes its name from Prometheus, who stole fire from the gods and gave it to humanity, then suffered eternal punishment for the gift. The parallel to radioactivity — powerful, useful, and dangerous — is deliberate. Mercury borrows from the Roman messenger god, reflecting the element's liquid fluidity and quicksilver movement. The element was known in ancient China, Egypt, Greece, and India, making it one of the oldest known elements.

Vanadium is named for Vanadis, the Norse goddess of beauty, because its compounds produce strikingly beautiful colors. Niobium comes from Niobe, daughter of Tantalus in Greek mythology (tantalum, the element above niobium in Group 5, is named for Tantalus himself). Palladium honors the asteroid Pallas, named for the Greek goddess Pallas Athena. Cerium references the dwarf planet Ceres, discovered just two years before the element.

Properties as Names

Some names skip mythology and history entirely, describing the element itself. Chlorine comes from the Greek "chloros" meaning pale green — the exact color of chlorine gas. Argon derives from "argos" meaning idle or lazy, because it absolutely refuses to react with other elements. Bromine comes from "bromos" (stench), and anyone who has smelled bromine vapor — a dark, choking, reddish-brown gas — can confirm the name is generously understated.

Phosphorus means "light-bearer" in Greek because white phosphorus glows eerily in the dark when exposed to air. Chromium comes from "chroma" (color) because its compounds span nearly every color of the rainbow. Iridium takes its name from Iris, the Greek goddess of the rainbow, for the same reason — its salts produce diverse colors.

Hydrogen means "water-maker" (hydro + genes), because burning hydrogen produces water. Oxygen means "acid-maker" (oxy + genes), reflecting an early — and incorrect — belief that all acids contain oxygen. The name stuck anyway.
