This article gives a new criterion for superconductivity. It can be applied to all the ele-ments in periodic table. The criterion shows that the values of electronegativity of all superconducting elements concentrate in a narrow range from 1.3 to 1.9 and that the elements with values outside this region would be non-superconductive.Deepgoing studying the relation between electronegativity and superconductivity of elements will contribute to revealing the connection between electrostatic inter action of electron with crystal lattice and superconductivity, which is able to benefit further inquiries about the mechanism of superconductivity.
