Which of the following atomic numbers (which are the same as the number of electrons in a neutral atom)correspond to an electronic ground-state configuration which ends in "..p³"? A)7,15,33 B)7,15,35 C)7,17,35 D)5,15,31 E)5,13,31

Question

Quizplus · Accepted Answer

The electron configuration "..p³" indicates that there are 5 electron orbitals occupied, with the highest energy orbital being a p orbital with 1 electron. Looking at the options, the only choice that has a p orbital with 1 electron in the highest energy level is option C, which corresponds to the elements chlorine (atomic number 17), sulfur (atomic number 16), and bromine (atomic number 35). However, sulfur has only 4 electron orbitals occupied in its ground state, so it cannot be the correct answer. Therefore, the correct answer is choice C, which corresponds to the elements chlorine and bromine.
