The letter “J” is the only one not found in the periodic table. In some countries (e.g., Norway, Poland, Sweden, Serbia, Croatia), the element iodine is known by the name jod. However, the periodic table still uses the IUPAC symbol I for the element.
The letter “Q” does not appear in any official element names. Temporary element names, such as ununquadium, contain this letter. However, no element name starts with Q and no official element name contains this letter. The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties.
Although it is not the only letter of the alphabet that is not within the Periodic Table of the chemical elements because the letter “ñ” is not found either. The “J” is a letter used internationally but the “ñ” is only Latin and is a product to a very simple and common factor that many would seem absurd but with an irrefutable logic.
The reasonable determination is that the names of the chemical elements are an abbreviation, but this abbreviation is associated with their Latin names, and the “J” did not exist in Latin, rather the “J” is a transformation that suffered the letter “I”, this explains that the letter “j” in lowercase also has a point above. Initially it was known as “I” Dutch. In other places it is known as “i” long, the truth is that the current name “jota” may have been taken from the “iota” which is a Greek letter.
