# Question

Assume that we are in another universe with different physical laws. Electrons in this universe are described by four quantum numbers with meanings similar to those we use. We will call these 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 integer values and q # p.

r takes on all even integer values from -q to +q. (Zero is considered an even number.)

s = + 1/2 or – 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 XY, XY2, X2Y, XY3, and X2Y3.

d. How many electrons can have p = 3?

e. How many electrons can have p = 4, q = 3, r = 2?

f. How many electrons can have p = 4, q = 3?

g. How many electrons can have p = 3, q = 0, r = 0?

h. What are the possible values of q and r for p = 5?

i. How many electrons can have p = 6?

q takes on positive odd integer values and q # p.

r takes on all even integer values from -q to +q. (Zero is considered an even number.)
