II. KCl should have a greater lattice energy than BeO.
III. The Lewis symbol Mg is correct for a magnesium atom.

Quizplus · Accepted Answer

I. The Lewis symbol of boron has 3 valence electrons, which are represented by three dots around the Boron symbol, which is correct.
II. KCl has a greater lattice energy than BeO due to the higher charge of K+ and Cl- ions compared to Be2+ and O2- ions.
III. The Lewis symbol for Mg has two valence electrons, which are represented by two dots around the Magnesium symbol, which is correct.
