A
Nitrogen (N)
B
Arsenic (As)
C
Bismuth (Bi)
D

Verified step by step guidance1
Identify the elements in Group 15 of the periodic table: Nitrogen (N), Phosphorus (P), Arsenic (As), Antimony (Sb), and Bismuth (Bi).
Recall that Group 15 elements include nonmetals, metalloids, and metals. Nitrogen and phosphorus are nonmetals, arsenic and antimony are metalloids, and bismuth is a metal.
Understand that metals typically have properties such as high electrical conductivity, malleability, and metallic luster, which are characteristic of bismuth in this group.
Compare the physical and chemical properties of each element to classify them as nonmetal, metalloid, or metal.
Conclude that among the given options, bismuth (Bi) is the Group 15 element classified as a metal.
