Question

The electronegativity for some elements on pauling scale of different groups and periods are listed below. Plot these values against atomic number. From the pattern, explain the variation along a period and a group

Answer 1

The concept of electronegativity was introduced by Linus Pauling in 1932; on the Pauling scale, fluorine is assigned an electronegativity of 3.98, and the other elements are scaled relative to that value.
