Pauling observed that the bond formed between atoms of different electronegativity where stronger than expected. Bond strength is due to two factors: covalent bonding between atoms and additional binding produced by an attraction between the oppositely charged ends of the bond dipole. Pauling used this concept (relative bond strengths) to devise his electronegativity scale.
As you look at the periodic table, the electronegativity INCREASES from left to right and DECREASES from top to bottom.

This is an arbitrary scale.
This largest value is '4' for Fluorine, which is the most electronegative element. All the other values are greater than zero, but some elements such Francium show only a very small degree of electronegativity '0.3' or there abouts.
All values are between 0 (zero) and 4.
