Give the set of four quantum numbers that could represent the last electron added (using the Aufbau principle) to the Sr atom. a. n = 4, I = 1, mI = -1, ms = +1/2.
b. n = 4, I = 1, mI = -1, ms = -1/2.
c. n = 4, I = 1, mI = 0, ms = -1/2.
d. n = 5, I = 1, mI = 1, ms = +1/2.
e. n = 5, I = 1, mI = 0, ms = +1/2.

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
