The higher the associated electronegativity number, the more an element or compound attracts electrons towards it. First proposed by Linus Pauling in 1932 as a development of valence bond theory, it has been shown to correlate with a number of other chemical properties. — “Electronegativity - Wikipedia, the free encyclopedia”, en.wikipedia.org
Pauling decided that his way of measuring attraction of electrons was to start with fluorine, the most electronegative element, and give it a value of 4. The electronegativity of all other elements would be determined by comparing them to fluorine. [change] References. — “Electronegativity - Simple English Wikipedia, the free”, simple.wikipedia.org
