The ions involved are Li\u207a and O\u00b2\u207b. Since the charge on oxygen is higher than that of nitrogen in Li3N, there is a relatively strong electrostatic attraction between Li\u207a and O\u00b2\u207b. However, the size of the O\u00b2\u207b ion is relatively large, which reduces the lattice energy slightly.<\/li>\n\n\n\n<li><strong>Li3N (Lithium Nitride):<\/strong> Here, lithium (Li) has a +1 charge, and nitrogen (N) has a -3 charge. The nitrogen ion (N\u00b3\u207b) carries a higher negative charge than oxygen, resulting in a much stronger electrostatic attraction between Li\u207a and N\u00b3\u207b. Additionally, the nitrogen ion is smaller than the oxide ion, which increases the lattice energy even further.<\/li>\n<\/ol>\n\n\n\n<p>The combination of a higher charge on the nitrogen ion and its smaller size compared to oxygen gives <strong>Li3N<\/strong> a higher lattice energy than <strong>Li2O<\/strong>.
