The melting point of KF (860 celcius) is greater than the melting point of potassium chloride (773 C) becasue:

answer F- has a smaller radius than Cl-

Explanation:

F- has smaller radius than does Cl-, the strength of the electrostatic coluomb force is greater in KF than KCl.

I thought that Coulomb forces depends on charge? and not mass? What am I missing here?

F = kq1q2/r^2

because the radius is smaller, the force is larger

oh wasn't thinking about the radius, knew there was something I was missing lmao...
