Defining Electronegativity
Electronegativity is the ability of an atom to attract a pair of electrons towards itself in a covalent bond
This phenomenon arises from the positive nucleus’s ability to attract the negatively charged
electrons, in the outer shells, towards itself
The Pauling scale is used to assign a value of electronegativity for each atom
First three rows of the periodic table showing electronegativity values
Electronegativity generally increases across a period and decreases down a group
Fluorine is the most electronegative atom on the Periodic Table, with a value of 4.0 on the Pauling
Scale
It is best at attracting electron density towards itself when covalently bonded to another atom
