Question

based on their locations on the periodic table, which best compares the properties of the metalloids arsenic (as) and antimony (sb)? arsenic has a more metallic behavior than antimony because arsenics atoms have fewer electron shells. arsenic has a more metallic behavior than antimony because arsenics atoms have more electron shells. arsenic has a more nonmetallic behavior than antimony because arsenics atoms have more electron shells. arsenic has a more nonmetallic behavior than antimony because arsenics atoms have fewer electron shells.

Explanation:

Metallic character increases down a group in the periodic table. Antimony is below arsenic in the periodic table. As we move down a group, the number of electron - shells increases. Fewer electron - shells lead to a more nonmetallic behavior. Arsenic has fewer electron - shells than antimony, so it has a more nonmetallic behavior.

Answer:

Arsenic has a more nonmetallic behavior than antimony because arsenic's atoms have fewer electron shells.
