Identify the term 'representative element': These are elements found in the s and p blocks of the periodic table, excluding the transition metals.
Understand the term 'pnictogen': Pnictogens are elements in Group 15 of the periodic table, which includes nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi).
Locate the 3rd Period on the periodic table: The 3rd Period includes elements with atomic numbers 11 to 18, which are Na, Mg, Al, Si, P, S, Cl, and Ar.
Determine which of the elements listed is a pnictogen: From the 3rd Period, phosphorus (P) is the only element that belongs to Group 15, making it a pnictogen.
Verify that phosphorus (P) is a representative element: Since phosphorus is in the p block of the periodic table, it is indeed a representative element.
