Which of the following species is paramagnetic : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: The stability of an ionic crystal is a measure of the energy required to break the crystal lattice into its constituent gaseous ions. Step 2: This stability is represented directly by the lattice energy of the crystal (the potential energy of the 3D electrostatic lattice). Step 3: Thus, the stability of an ionic crystal principally depends on the lattice energy of the crystal, which corresponds to option (b).
