Question

based on their locations on the periodic table which best compares the properties of the metalliods arsenic (As) and antimony (Sb )

Answer 1

Metallic Characteristics: solid at room temperature, lustrous

In Between Characteristics: amphoteric, semiconducting

Nonmetallic: brittle

Answer 2

In order to compare the two elements, one must take note of

its placement in the periodic table. As you go down a group in the periodic

table, the metallic property increases. Thus in the problem, Antimony has a

more metallic behavior than Arsenic so that already crosses out statement A and

B from the choices since it is untrue. The number of electron shells meanwhile

decreases as you go down the group. Therefore the answer would be Arsenic has a

more nonmetallic behavior than antimony because arsenic’s atoms have fewer

electron shells.
