[Answer] The table lists the lattice energies of some compounds.Which statement about crystal lattice energy is best supported by the information in the table?

Answer: a. The lattice energy increases as cations get smaller as shown by LiF and KF.

The unit cell for each crystal structure is the smallest group of atoms which has the overall symmetry of the crystal and from which the entire crystalline lattice can be built up by repetition in three dimensions. In the case of the body-centered cubic crystal structure shown above the unit cell is made up of the central atom plus one-eight of each of the eight corner atoms.

A crystal or crystalline solid is a solid material whose constituents (such as atoms molecules or ions) are arranged in a highly ordered microscopic structure forming a crystal lattice that extends in all directions. In addition macroscopic single crystals are usually identifiable by their geometrical shape consisting of flat faces with specific characteristic orientations.

Platinum is a moderately hard metal (MH 3.5) of low mechanical strength with a close-packed face-centred cubic structure (BCN 12). Compared to other metals in this category it has an unusually high melting point (2042 K v 1338 for gold). Platinum is more ductile than gold silver or copper thus being the most ductile of pure metals but it is less malleable than gold.

A hypervalent molecule (the phenomenon is sometimes colloquially known as expanded octet) is a molecule that contains one or more main group elements apparently bearing more than eight electrons in their valence shells. Phosphorus pentachloride (PCl 5) sulfur hexafluoride (SF 6) chlorine trifluoride (ClF 3) the chlorite (ClO 2 −) ion and the triiodide (I 3 −) ion are examples of …

Because the lanthanide ions have slightly different radii the lattice energy of their salts and hydration energies of the ions will be slightly different leading to a small difference in solubility. Sa…
