The letter J and Q room not uncovered on the periodic table.

You are watching: Only letter not on periodic table

The letters “J” and “Q” room the only two letters not discovered on the regular table. This letters do not happen in either element symbols or facet names. However, you can find both letters on the regular table in the past and also may find them still on particular charts.

The Letter J ~ above the regular Table

The letter J was the aspect symbol for iodine in Mendeleev’s 1871 periodic table.

You won’t discover the letter “J” top top the IUPAC regular table that the elements. However, J to be the symbol for the aspect jod or iodine on Mendeleev’s routine table. In some countries (e.g., Norway, Poland, Sweden, Serbia, Croatia), the element iodine is well-known by the name jod, even though the international aspect symbol is I. The German word for iodine is Iod or Jod (nouns are constantly capitalized in German). The Jod-Basedow impact gets its surname from the aspect Jod and also the name of the doctor who very first described the syndrome. The Jod-Basedow effect is hypothyroidism result from administration of iodide or iodine.

Many human being thought the discovery of aspect 113 by the Japanese RIKEN team would result in an element name start with the letter J. But, the researcher went with the surname nihonium through symbol Nh, honoring the Japanese surname for their country, Nihon koku.

The Letter Q ~ above the periodic Table

The letter “Q” go not occur in any official aspect name. However, it was the short-term or placeholder name for element 114. After ~ its main discovery, aspect 114 was called flerovium. Its placeholder surname was ununquadrium, which way “one one four.” The extended periodic table, which has undiscovered elements, still includes the letter Q. The placeholder surname for aspect 124 is unbiquadium, with aspect symbol Ubq.

IUPAC rules for temporary Names

IUPAC short-lived names define undiscovered facets by your atomic number. The only way an aspect will obtain a “J” in its surname is if a discoverer choose the letter, yet the letter “Q” wake up in any temporary surname containing the number four:
