# The strongest interactions in the compound sodium fluoride, NaF, are an example of what type of bond?

During the formation of $\text{NaF}$, the sodium atom loses its single valence electron, forming a sodium ion with a ${1}^{+}$ charge. The fluorine atom gains the electron from the sodium atom, forming a fluoride ion with a charge of 1^(-)". The electrostatic attraction between the oppositely charged ions forms the ionic bond.
