Fe electronegativity value
WebPeriodic Trends in the Electronegativities of Elements. As we move across a period from left to right the nuclear charge increases and the atomic size decreases, therefore the value of electronegativity increases across a … WebCh 1: Electronegativity. Electronegativity. Electronegativity is defined as the ability of an atom to attract electrons towards itself. It is one of the most important properties for rationalising and predicting reactivity etc. The partial periodic table below has the Pauling electronegativities of some key elements. H.
