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.

electron shielding. the reduction of the attractive force between a positively charged nucleus and its outermost electrons due to the cancellation of some of the positive charge with the negative charge of the other electrons.
