E)5

Question

Quizplus · Accepted Answer

The maximum angular momentum quantum number for any electron in the ground state electron configuration can be determined using the formula L= n - 1, where n is the principal quantum number. The ground state electron configuration for iodine is [Kr] 5s2 4d10 5p5. The highest value for n in this configuration is 5, which corresponds to the 5p sublevel. Therefore, the maximum possible value for L in the ground state configuration of iodine is 5-1= 4. Hence, the correct choice is D.
