🤓 Based on our data, we think this question is relevant for Professor Dixon's class at UCF.
We are being asked to identify which compound has a higher magnitude lattice energy between NaCl and MgCl2
Radius = period number
• To determine the cation and anion charge, recall that some elements have common charges based on what group they belong to on the periodic table:
Group 1A +1 charge
Group 2A +2 charge
Group 3A +3 charge
Group 4A typically do not gain or lose e- until Tin (Sn) and Lead (Pb)
Group 5A -3 charge
Group 6A -2 charge
Group 7A -1 charge
• For their cation and anion radius, refer to the periodic table to determine which period the atom belongs to
Calculate the Lattice Energy (Ionic Bond Energy) of each compound given:
▪ Group 1A → +1 charge → Na+
▪ Period = 3
▪ Group 7A → -1 charge → Cl-
▪ Period = 3
Ionic Bond Energy = 0.17
Which compound has a higher magnitude lattice energy: NaCl or MgCl2?
