The mechanism of action of probiotics (e.g., having an impact on the intestinal microbiota or enhancing immune function) was dropped from the definition to encompass health effects due to novel mechanisms and to allow application of the term before the mechanism is confirmed.
Noun. 1. electronegativity - (chemistry) the tendency of an atom or radical to attract electrons in the formation of an ionic bond. negativity.
Electronegativity is useful for all elements on the periodic table but it is most useful for the nonmetals, which are shown here to the right. Electronegativity is more of a concept than a property.As such, values for it are estimated or calculated rather than measured.ere is one particular set of values. Look at how the electronegativity changes as you go across and up and down the periodic table (for nonmetals,right, and all elements, below). No values are given for the inert gases because they do not bond readily to other atoms.
