Write the Lewis symbol for each atom or ion. a. \(s^{2-}\) b. \(\mathrm{Mg}\) c. \(\mathrm{Mg}^{2+}\) d. \(P\)
A fundamental difference between compounds containing ionic bonds and those containing covalent bonds is the existence of molecules. Fiplain why molecules exist in solid covalent compounds but not in solid ionic compounds.
Write the Lewis structure for each molecule or ion. a. \(\mathrm{H}_{3} \mathrm{COCH}_{3}\) b. CN c. \(\mathrm{NO}_{2}^{-}\) d. \(\mathrm{ClO}^{-}\)
Use Lewis structures to explain why \(\mathrm{Br}_{3}^{-}\) and \(\mathrm{I}_{3}^{-}\) are stable, while \(\mathrm{F}_{3}{ }^{-}\) is not.
Rubidium iodide has a lattice energy of \(-617 \mathrm{kj} / \mathrm{mol},\) while potassium bromide has a lattice energy of \(-671 \mathrm{~kJ} / \mathrm{mol}\). Why is the lattice energy of potassium bromide more exothermic than the lattice energy of rubidium iodide?
