摘要：
In this paper is presented a feature exhibited by all superconductors, a correlation of the critical temperature with the averaged electronegativity of the elements. The low- T-c superconductors electronegativity values are centered around 1.8, with a range from 1.2 to 2.3. For high-T-c, superconductors the averaged electronegativity around 2.5 gives the highest critical temperatures, the overall range of electronegativity for cuprates being between 2.43 and 2.68.
