The difference in electronegativity between silicon, $S i$, and fluorine, $F$, is equal to 2.08.

According to the Pauling electronegativity scale, silicon has an electronegativity value of 1.90. Fluorine, which is the most electronegative atom, has an electronegativity value of 3.98.

As a result, the difference between the two will be

$\Delta E N = E {N}_{\text{fluorine" - EN_"silicon}}$

$\Delta E N = 3.98 - 1.90 = \textcolor{g r e e n}{2.08}$
