The decreasing order of ionic radius of the given ions needs to be determined. O, O - , O 2- Concept Introduction: The periodic properties of the element can be determined with the help of their position in the periodic table and also with their valence shell electronic configuration. The energy that is required to remove an electron from the neutral gaseous atom is called as ionization energy. Across the period, the atomic size decreases that increase the ionization energy across the period whereas as the atomic size increases down in the group the ionization energy decreases.

Question

Mixing SbCl 3 and GaCl 3 in a one-to-one ratio gives a solid ionic compound of empirical formula GaSbCl 6 . A controversyerupts over whether this compound is [SbCl 2 ] + [GaCl 4 ] ─ or [GaCl 2 ] + [SbCl 4 ] ─ . It is learned that the cation in the compound has abent structure. Based on this fact, which combination is more likely to be correct? Explain.
