Based on their locations on the periodic table, which best compares the properties of the metalloids arsenic (As) and antimony (Sb)?

A. Arsenic has a more metallic behavior than antimony because arsenic's atoms have fewer electron shells.
B. Arsenic has a more metallic behavior than antimony because arsenic's atoms have more electron shells.
C. Arsenic has a more nonmetallic behavior than antimony because arsenic's atoms have more electron shells.
D. Arsenic has a more nonmetallic behavior than antimony because arsenic's atoms have fewer electron shells.



Answer :

Final answer:

Arsenic has a more nonmetallic behavior than antimony due to arsenic's atoms having more electron shells.


Explanation:

Arsenic and antimony are both metalloids with properties that fall between metals and nonmetals. While both have similar properties due to being metalloids, arsenic tends to exhibit a more nonmetallic behavior than antimony because arsenic's atoms have more electron shells compared to antimony, which influences their chemical behaviors and reactivity.
