which of the following atoms has the largest atomic radius? choose 1 answer: a nitrogen b phosphorous c antimony
Answer
Explanation:
Step1: Recall atomic - radius trend
Atomic radius increases down a group in the periodic table.
Step2: Locate elements in periodic table
Nitrogen (N) is in Group 15, Period 2; Phosphorus (P) is in Group 15, Period 3; Antimony (Sb) is in Group 15, Period 5.
Step3: Compare atomic radii
Since Sb is the lowest - placed among the three in the group, it has the largest atomic radius.
Answer:
C. antimony
