Like the periodic table, the list below organizes the elements by the number of protons in their atoms; it can also be organized by other properties, such as atomic weight, density, and electronegativity. For more detailed information about the origins of element names, see List of chemical element name etymologies.
Dilithium, Li 2, is a strongly electrophilic, diatomic molecule comprising two lithium atoms covalently bonded together. Li 2 has been observed in the gas phase.It has a bond order of 1, an internuclear separation of 267.3 pm and a bond energy of 102 kJ/mol or 1.06 eV in each bond. [1]
The name dilithium has led to speculation on whether it is meant as an isotope of lithium or a compound with two lithium atoms. [36] But in a periodic table in a Next Generation episode, it is shown as an element with chemical symbol Dt and atomic number 87, which is in reality francium.

The currently accepted names and symbols of the chemical elements are determined by the International Union of Pure and Applied Chemistry (IUPAC), usually following recommendations by the recognized discoverers of each element. However, the names of several elements have been the subject of controversies until IUPAC established an official name.
Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3; it is usually shown at the foot of the table to save horizontal space.
