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.

A higher electronegativity means that the atom will attract bonded electrons to it more strongly. The electronegativity of an atom is a measure of the ability of the atom in a molecule to attract shared electrons to itself. Electronegativity values have been calculated for every atom in the periodic table.he electronegativity of atoms increases as we move from left to right across a period in the periodic table. As we move from left to right across a period the nuclear charge is increasing faster than the electron shielding, so the attraction that the atoms have for the valence electrons increases.
