WebQuestion: The lattice energy of a salt is related to the energy required to separate the ions. For which of the following pairs of ions is the energy that is required to separate the ions largest? (Assume that the distance between the ions in each pair is equal to the sum of the ionic radii.)(A) Na+(g) and Cl−(g) (B) Cs+(g) and Br−(g) (C) Mg2+(g) and O2−(g) (D) Web8 mei 2024 · Ionic radii follow the same vertical trend as atomic radii; that is, for ions with the same charge, the ionic radius increases going down a column. The reason is the same as for atomic radii: shielding by filled inner shells produces little change in the effective nuclear charge felt by the outermost electrons.

WebWe summarize the important points about ionic bonding: At r0, the ions are more stable (have a lower potential energy) than they are at an infinite internuclear distance. When oppositely charged ions are brought together from r = ∞ to r = r0, the energy of the system is lowered (energy is released). WebMar 24,2024 - The ionic radii of Cs+ and Cl- ions are 181 and 167 pm, respectively. The Born exponents for the He, Ne, Ar, Kr and Xe configurations are 5, 7, 9, 10 and 12, respectively.
