which statements describe lattice energy?\nit is the energy the ions absorb when they form a crystalline compound.\nit increases as the size of the ions decreases.\nit increases as the charge on the ions increases.\nit explains why ions form molecules.\nit is a measure of the strength of the bonds between ions in a compound.\ndone
Answer
# Brief Explanations:
- Lattice energy is the energy released when ions form a crystalline compound (not absorbed), so the first statement is wrong.
- According to Coulomb's law \(E = k\frac{q_1q_2}{r}\) (where \(q\) is the charge of ions and \(r\) is the distance between ions which is related to ion size), as ion size (\(r\)) decreases, lattice energy (\(E\)) increases.
- As the charge (\(q\)) on ions increases, lattice energy (\(E\)) increases (from Coulomb's law).
- Lattice energy is about ionic compounds (not about ions forming molecules).
- Lattice energy is a measure of the strength of ionic bonds (bonds between ions in a compound).
# Answer:
- Second statement: "It increases as the size of the ions decreases."
- Third statement: "It increases as the charge on the ions increases."
- Fifth statement: "It is a measure of the strength of the bonds between ions in a compound."
