Q

What are the 2 properties that electrostatic attractions depend on?

A
  1. Charge of the ions
  2. Ionic radius
17
Q

How does the charge of the ions affect the strength of the electrostatic attractions?

A

The higher the charge, the stronger the attraction

18
Q

How does the size of the ion (ionic radius) affect the strength of the electrostatic attractions?

A

The smaller ions have stronger attractions

higher up and to the right of the periodic table, the smaller the ion becomes
