a.For element X in the ground state the number of unpaired electrons is the same as the maximum number of electrons in an atom that can have the quantum number designations n =2,
mt= -1, and m, =--21.
b. Let A equal the charge of the stable ion that would produce when the undiscovered element 120 forms the ionic compounds. This value of A also represents the angular momentum quantum number for the sub shell which is having the unpaired electron(s) for element X.
Using the following information, find out the strong electrolyte whose general formula is
Mx (A)y . zH2O
a. A"-is a common oxidation. When 30.0 mg of the anhydrous sodium salt having this oxyanion (Na, A, where n =1, 2, or 3) is reduced, 15.26 mL of 0.02313 M reducing agent is needed to react totally with the Na, A present. Suppose a 1: 1 mole ratio in the reaction.
