Elactrostatic force of attraction between sodium ion and halide ion is greatest in
NaCI
NaBr
NaF
NaI
Forklaring
The electrostatic force of attraction is greatest depending on their strength of electronegativity. In other words, Fluorine atom has the highest electronegativity as it is the most reactive non-metal. The electrostatic force of attraction is greatest between Na and F. The correct answer is option C.
