Only 1 alphabet will not appear in periodic table?
The letter "J" is the only one not found on the periodic table
Note that 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. Once the final four elements on the present periodic table get official names, there will be no Q on the periodic table. The extended periodic table, which includes undiscovered superheavy elements (atomic numbers greater than 118), would still contain the letter Q in temporary element names.
