- 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.
The answer is Arsenic has a more nonmetallic behavior than antimony because arsenic's atoms have fewer electron shells (4th option).
