Question

Quizplus · Accepted Answer

The electron configuration given corresponds to the element sulfur (S), which is in period 3 and group 16. However, the question asks for the period and group of an element with this electron configuration. To determine the period, we count the highest value of n in the configuration, which is 4. Therefore, the element belongs in period 4. To determine the group, we count the number of valence electrons, which is 6. Counting from the left-hand side of the periodic table, we find that group 16 has elements with 6 valence electrons, so the element belongs to group 16. Therefore, the correct answer is A) period 4; group 16.
