Correct Answer: Pauling scale
Solution : The correct option is the Pauling scale.
This scale was developed by Linus Pauling. The Pauling electronegativity scale quantifies the ability of an atom to attract electrons in a chemical bond. It's a dimensionless scale. Fluorine is set to 4.0 as it is the most electronegative element, and the reference for cerium is set to 0.7.
