A
Nitrogen (N)

Verified step by step guidance1
Identify the group 5A elements in the periodic table. Group 5A (also called group 15) includes Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb), and Bismuth (Bi).
Understand what a semimetal (or metalloid) is: an element with properties intermediate between metals and nonmetals, often found along the zig-zag line dividing metals and nonmetals on the periodic table.
Check the classification of each group 5A element: Nitrogen (N) and Phosphorus (P) are nonmetals, Antimony (Sb) and Arsenic (As) are semimetals, and Bismuth (Bi) is a metal.
Since the problem asks for a semimetal in group 5A, focus on Arsenic (As) and Antimony (Sb), both semimetals in this group.
Confirm that Arsenic (As) is the correct answer as it is a well-known semimetal located in group 5A, matching the problem's requirement.
