Answer:
It is more electronegative
Explanation:
Fluorine is able to pull the electron away from Lithium because it a more electronegative specie.
Electronegativity is a measure of the relative tendency with which the atoms of the element attracts valence electrons in a chemical bond.
- The more electronegative a specie is, the more its tendency to pull electrons.
- Based on the Pauling's electronegativity table of elements, Li has an electronegative value of 1.0 and fluorine has 4.0
- Fluorine is the most electronegative element.
- It will attract the electrons better.
