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

Question

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

Answer 1

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