21.How many electrons in an atom can have of the following quantum number or sublevel designations?(choosing the correct answers)(I) n = 2,I = 1. (II) 3d. (III) 4s. (IV) 4p. (V) n = 3. I = 1,m1 = 1. (VI) n=5, I=3.
(A)(I) + (II) = 15e-
(B)(III) + (IV) = 8e-
(C)(V) + (VI) = 15e-
(D)(I) + (II) + (V) = 10e-
(E)(II) + (IV) + (VI) = 28e-
