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.

1 In 1932 Linus Pauling defined electronegativity as the power of an atom in a molecule to attract electrons to itself. 2  Pauling devised a numerical electronegativity scale, based on bond energies. 3  In general, electronegativities decrease down a Group of the Periodic Table.ey Concepts. 1  In 1932 Linus Pauling defined electronegativity as the power of an atom in a molecule to attract electrons to itself. 2  Pauling devised a numerical electronegativity scale, based on bond energies. 3  In general, electronegativities decrease down a Group of the Periodic Table.
