Question

when ions come together to form a crystal, energy is released. which of the following best describes this energy A) ionic energy. B) Lattice Energy. C) Ionization Energy. D) Deactivation Energywhen ions come together to form a crystal, energy is released. which of the following best describes this energy A) ionic energy. B) Lattice Energy. C) Ionization Energy. D) Deactivation Energy

Answer 1

Answer: Option (B) is the correct answer.

Step-by-step explanation:

Lattice energy is defined as the energy released when formation of 1 mole of an ionic compound occurs due to the combination of its constituent ions.

Hence, more is the magnitude of lattice energy more will be the stability of the ionic compound.

Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.

Thus, we can conclude that the statement when ions come together to form a crystal, energy is released best describes lattice energy.

Answer 2

When a cation ad anion came close to each other from infinity and formation of a crystal occur, due to the electrostatic attraction between them, an amount of energy is being released, and forms a stable crystal, this released energy is called lattice energy. Lattice energy decreases down to group and increase left to right. Thereby, the correct option is B.
