Electronegativity

Electronegativity
 
the ability of an atom or a functional group to attract electrons (or electron density) towards itself.
 
The higher the associated electronegativity number, the more an element or compound attracts electrons towards it.
 
Electronegativity cannot be directly measured and must be calculated from other atomic or molecular properties. It is commonly calculated as a dimensionless quantity: the Pauling scale, on a relative scale running from 0.7 to 4.0 (hydrogen = 2.2).
 
The equivalent property of a free atom is its electron affinity
