Interest in probiotics is at an all-time high in the United States, driven in part by new products emerging in the market, by US researchers eager to evaluate efficacy claims rigorously, and by consumers interested in potential therapeutic and preventive health benefits.
Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is given a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7.lectronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Fluorine is the most electronegative element. It has a charge of -1 and readily forms compounds. Original author unknown, Creative Commons License (Wikipedia). Anne Marie Helmenstine, Ph.D.ther highly electronegative elements are oxygen and chlorine. The element hydrogen does not have as high of an electronegativity because, although it has a half-filled shell, it readily loses an electron rather than gains one.
