* Electronegativity is a chemical property that describes the tendency of an atom to attract electrons (or electron density) towards itself.
* * Ionization Energy (IE) is qualitatively defined as the amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation.
