Question

Quizplus · Accepted Answer

The first shell, labeled as n=1, can only hold up to a maximum of 2 electrons and has one subshell, labeled as s. The second shell, labeled as n=2, has both an s and a p subshell, allowing for a total of 8 electrons. The h orbital belongs to the third shell, labeled as n=3, which has four subshells (s, p, d, f) and can hold up to a maximum of 18 electrons. Therefore, the first shell in which an h orbital would be allowed is the third shell, making option B the correct answer.
