PLEASE 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 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.
