The tendency of an atom to pull electrons toward itself is referred to as its _____. ionic potential tonicity covalency electron
larisa86 [58]

Electronegativity

The tendency of an atom to pull electrons towards itself is called electronegativity.

It is the tendency of an atom to attract bonding pair of electrons towards itself. These atoms which are more electronegative are able to bear a negative charge and be stable.

Unlike electropositive elements which tend to lose electrons , electronegative elements hold on tightly to the electrons.

The electronegativity is measured using the Pauling Scale where the most electronegative element of the periodic table, Fluorine , is given a value of 4 and the rest of the elements have values lower than 4 according to the trends followed by their groups and periods.

The least electronegative element of the periodic table , Cesium has a value of 0.7 on the Pauling Scale.

Electronegativity increases when we move from left to right in the periodic table and it decreases (in general) when we move down the group.
