In another universe the electrons are described by four quantum numbers p, q, r, and s. The rules for these quantum numbers are as follows. • p = 1, 2, 3, 4, 5, ...; • q takes on positive odd integers and q ≤ p; • r takes on all even integer values from - q to + q; • s = ±1/2. (a) Sketch what the first four periods of the periodic table will look like in this universe. (b) What are the atomic numbers of the first four elements you would expect to be least reactive? (c) Give an example, using elements in the first four rows, of ionic compounds with the formulas, of ionic compounds with the formulas XY, XY2, X2Y, XY3, and X2Y3. (d) How many electrons can have p = 4, q = 3? (e) How many electrons can have p = 3, q = 0, r = 0? (f) How many electrons can have p = 6?
