Lattice Energy Practice

Front

What is lattice energy?

Back

Lattice energy is the amount of energy released when gaseous ions combine to form an ionic solid. It is also the energy required to separate one mole of a solid ionic compound into its gaseous ions.

Front

What factors affect lattice energy?

Back

Lattice energy is affected by the size of the ions and the charges of the ions. Smaller ions and ions with higher charges result in greater lattice energy.

Front

How does ionic bond formation occur?

Back

Ionic bonds form between a metal and a nonmetal, where the metal donates electrons to the nonmetal, resulting in the formation of positively and negatively charged ions.

Front

What is the formula for the compound formed from Fe (III) ion and chlorine?

Back

FeCl₃

Front

Which ionic compound has a greater magnitude of lattice energy: NaCl or CsI?

Back

NaCl has a greater magnitude of lattice energy than CsI.

Front

Order the following ionic compounds by decreasing lattice energy: Al₂S₃, BaI₂, KBr, NaF, MgO.

Back

Al₂S₃, MgO, BaI₂, NaF, KBr.

Front

What is the significance of ion size in lattice energy?

Back

Smaller ions can pack closer together, leading to stronger electrostatic forces and higher lattice energy.

Front

What role do ion charges play in determining lattice energy?

Back

Higher charges on ions increase the electrostatic attraction between them, resulting in higher lattice energy.

Front

Define ionic compound.

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding.

Front

What is the relationship between lattice energy and the stability of an ionic compound?

Back

Higher lattice energy indicates greater stability of the ionic compound due to stronger attractions between the ions.
