Identify the period number given: Period 5. This refers to the fifth row of the periodic table, indicating the principal energy level (n=5) of the element's valence electrons.
Recall the elements in Group 15 (5A) across the periods: Nitrogen (N) in period 2, Phosphorus (P) in period 3, Arsenic (As) in period 4, Antimony (Sb) in period 5, and Bismuth (Bi) in period 6.
Match the element located in Group 15 and Period 5, which is Antimony, with its atomic symbol 'Sb'.
Confirm that 'Sb' is the correct atomic symbol for the element in Group 5A (15) and Period 5, distinguishing it from the other options provided.
