Electronegativity refers to the tendency in which an tom would attract electrons to itself.
Below each element in the periodic table is their electronegativity value. Florine has the highest electronegativity value of 4.0.
Going through options;
A. Florine has a stronger pull than Magnesium

Phosphorus = 2.1
This is wrong
C. Potassium has a stronger pull than Sodium
