In solid KCI the smallest distance between the centers of a. potassium ion and a chloride ion is 314 pm. Calculate the length of the edge of the unit cell and the density of KCI, assuming it has the same structure as sodium chloride.
You are tutoring a bright student in his last semester of
introductory physics. The particular topic of the day is
bonding in solids. When your session begins, the student
hands you a slip of paper with the following equation
printed on it:
U, = -ak,
1
m
He says that he found this equation in his online studying
and that it is described as an expression for the ionic cohesive
energy of a crystal formed by ionic bonding. He asks you to
derive this equation.
