Every element has a name and a chemical symbol of one or two letters. This periodic table shows the name, symbol and atomic number of all 118 elements, from hydrogen (H) to oganesson (Og), and the list below can be sorted alphabetically or by atomic number.

How element symbols work

A chemical symbol is a short code that chemists use worldwide, whatever language they speak. It always starts with a capital letter, and any second letter is lowercase, which matters: Co is cobalt, while CO is carbon monoxide, a compound of carbon and oxygen. Since 2016 every element has a permanent name and symbol; before that, newly made elements had temporary three-letter symbols, such as Uuo for ununoctium, now oganesson.

Most symbols come from the element's English name, usually its first letter or two: H for hydrogen, C for carbon and Ca for calcium. When several names start with the same letter, a second letter tells them apart, as in Cl for chlorine and Cr for chromium.

Symbols that come from Latin

Eleven symbols do not match the English name because they come from older names, mostly Latin: Na for sodium (natrium), K for potassium (kalium), Fe for iron (ferrum), Cu for copper (cuprum), Ag for silver (argentum), Sn for tin (stannum), Sb for antimony (stibium), Au for gold (aurum), Hg for mercury (hydrargyrum, meaning water silver) and Pb for lead (plumbum). W for tungsten comes from wolfram, the element's name in German.

These are worth learning by heart because they appear constantly in formulas: table salt is NaCl, and iron(III) oxide, the main part of rust, is Fe₂O₃.

Where element names come from

Some names describe a property: chlorine comes from the Greek for pale green, bromine from the Greek for stench, and hydrogen means water-former. Others honor places, such as americium, francium and polonium; four elements, yttrium, terbium, erbium and ytterbium, are named after the Swedish village of Ytterby. Scientists are honored in einsteinium, curium and mendelevium, uranium, neptunium and plutonium are named after Uranus, Neptune and Pluto, and titanium and promethium come from Greek mythology.

New elements are named by their discoverers and approved by IUPAC, the International Union of Pure and Applied Chemistry. The most recent four, named in 2016, are nihonium, moscovium, tennessine and oganesson. New names end in -ium, except in group 17 (-ine, as in tennessine) and group 18 (-on, as in oganesson).

Using this view: copper

Type a name, symbol or atomic number into the filter box to find any element, then hover over or tap it to see its data. Search for Cu and you land on copper, atomic number 29, in group 11. Its symbol comes from cuprum, from the Latin for metal of Cyprus, an island famous for its copper mines in ancient times.

This site uses American spellings, so you will see aluminum and cesium. Elsewhere you may meet aluminium and caesium, the spellings IUPAC recommends, while sulfur is the IUPAC spelling everywhere.
