Question

What causes an element to be more electronegative than others? (Besides the electrons getting further from the positively charged nucleus and obtaining a noble gas configuration)

Answer 1

Electronegativity is described as an element's desire to attract electrons from other elements to attain the same electron configuration of a noble gas.


Covalent bonds are “characterized by the sharing of pairs of electrons between atoms, or between atoms and other covalent bonds”. With , the ability of elements to attract shared electrons, the more electronegative an element is the more energy it pulls itself toward that same element.
For example, C-F
F has the most electronegative , so therefore electrons gets to be pulled towards it.
