This is the case with the +1 ions of the alkali metals, silver, hydrogen, thallium, and copper. An element that is will be highly electronegative has: The original electronegativity scale, developed in the 1930s by Linus Pauling (1901 1994) was based on measurements of the strengths of covalent bonds between different elements. This gives them a charge of 1+. The most important method uses a measurement called electronegativity (represented by the Greek letter chi, , pronounced ky as in sky), defined as the relative ability of an atom to attract electrons to itself in a chemical compound.
