Answer:
Sure, here are the abbreviated electron configurations for each:
- Be: 1s² 2s²
- Sn: [Kr] 5s² 4d¹⁰ 5p²
- Be: 1s² 2s²
- F: 1s² 2s² 2p⁵
- F: 1s² 2s² 2p⁵
- Ti: [Ar] 4s² 3d²
- Sn²⁺: [Kr] 4d¹⁰
- Sn⁺: [Kr] 4d¹⁰ 5s²
- As: [Ar] 4s² 3d¹⁰ 4p³
- As³⁺: [Ar] 3d¹⁰
- Ti²⁺: [Ar] 3d²
- As³⁺: [Ar] 3d¹⁰
- Ti: [Ar] 4s² 3d²
- As: [Ar] 4s² 3d¹⁰ 4p³
- K: [Ar] 4s¹
- Zn: [Ar] 3d¹⁰ 4s²
- K: [Ar] 4s¹
- Mg²⁺: [Ne] 3s²
- Zn²⁺: [Ar] 3d¹⁰
- Ca²⁺: [Ar] 4s⁰
- Cr: [Ar] 4s¹ 3d⁵
Now, going back through the list and marking the atom or ion with the largest radius:
- Be: *
