Comments

Helium (2), neon (10) and argon (18) do not have electronegativity in Pauling scale, so they are omitted. If the data for two elements are the same then they are sorted by atomic number (for example, the data for scandium (21) and neptunium (93) are both 1.36 so 21 comes before 93). - Jianing Song, Oct 01 2018
