Below is a periodic table of electronegativity: the lighter the shade of green, the higher the electronegativity. Gray means no value is known. (Click image for larger view that shows electronegativity values.) Looking at the elements in the periodic table, in general, electronegativity of element...

electronegativity Thesaurus Medical Acronyms Encyclopedia Wikipedia (ɪˌlɛktrəʊˌnɛɡəˈtɪvɪtɪ) n 1.(General Physics) the state of being electronegative 2.(Chemistry) a measure of the ability of a specified atom to attract electrons in a molecule ...
Electron affinity is most often reported in units of kilojoule per mole (kJ/mol). Sometimes the values are given in terms of magnitudes relative to each other. If the value of electron affinity orEeais negative, it means energy is required to attach an electron. Negative values are seen for...
in Chemistry and has taught many at many levels, including introductory and AP Chemistry. Remember, periodic trends are just trends. There is some variation here and there, but aside from knowing the noble gases 'break the rules' of electronegativity, don't worry about memorizing the exceptions...
In the framework of density functional theory, a new formulation of electronegativity that recovers the Mulliken definition is proposed and its reliability... MV Putz,N Russo,E Sicilia - 《Theoretical Chemistry Accounts》 被引量: 70发表: 2005年 Enthalpies of formation of monoderivatives of hydrocarb...

Electronegativity- A measure of how readily an atom forms a chemical bond. Electronegativity increases moving left to right across a period and decrease moving down a group. Atomic Radius- This is half the distance between the middle of two atoms just touching each other. Atomic radius decreases...
The proportion of ionic/covalent behavior in a bond can be very roughly assessed using the Pauling scale of electronegativity. Linus Pauling estimated that an electronegativity difference of 1.7 between elements leads to bonding that is 50 percent ionic. Values below 1 correspond to covalent bonding...
