Given that the ions in LiF and in MgO are of similar in size which compound has stronger ionic bonding use Coulomb's law to explain

Solutions

Expert Solution

Ionic strength depends on attraction or repulsion that can be explained with Coulomb's law. Energy of attraction or repulsion between two particles is comparable to the multiplication of two charges and inversely comparable to the distance between two particles.

Ions in LiF and MgO have same size, this indicates the distance between 2 particles in compound is same. So, the thing that affect the ionic strength is the charge of each compound. Ions in LiF has smaller energy than MgO because MgO ions (Mg 2+ charge and O 2- charge) have bigger charge than the LiF (Li +1 and F -1 charge). Hence MgO has strong ionic bonding when compared to LiF.

The size of ions as measured by ionic radii varies in a systematic manner. The size of the ion can be explained in part by effective nuclear charge, Zeff, which is the net nuclear charge felt by an electron. The effective nuclear charge takes into account the actual nuclear charge and the shielding of this charge by inner electrons. When an atom loses electrons, the resulting cation is smaller both because the remaining electrons experience a larger Zeff and because...
