Chapter 9, Problem 9.72QP

Interpretation Introduction

Interpretation:

Some experiments have to be suggested to show that magnesium oxide consists of $M{g}^{2+}$ and $O^{2-}$ ions and not $M{g}^{+}$ and $O^{-}$ ions.

Concept Introduction:

A chemical compound or ion is said to be paramagnetic if it has electrons of unpaired spin and diamagnetic if it has electrons of paired spins.

The energy released when gaseous state ions of unlike charges that are infinitely farther apart combine to form a stable ionic solid is called Lattice energy.  Conversely, the energy required to break the electrostatic force of attraction between the ions of unlike charges in the ionic solid and revert them to gaseous state is also termed as Lattice energy of an ionic solid.
