Cations X,Y have pseudo-inert-gas configuration (18 electrons in their outermost shell) and inert-gas configuration respectively. Find the difference between their maximum possible charges. Their proton counts are between 20 and 31; after Mn, the possible cation charge is below +3. [Source wording retained; no answer is printed.]
Answer:
4.00
Solution:
Author-derived 4, not a printed key. Under a formal maximum-oxidation-state reading, Ga(+3) has pseudo-inert [Ar]3d¹⁰ configuration and Mn(+7) leaves [Ar]. The formal charges differ by 7-3=4. This does not claim that free monatomic Mn⁷⁺ is an ordinary chemical ion. The source has ambiguous 'cation charge' wording and supplies no answer.
