Answer:
Sure, here are the abbreviated electron configurations for each:
- Be: 1s² 2s²
- Sn: [Kr] 5s² 4d¹Ⱐ5p²
- Be: 1s² 2s²
- F: 1s² 2s² 2pāµ
- F: 1s² 2s² 2pāµ
- Ti: [Ar] 4s² 3d²
- Sn²āŗ: [Kr] 4d¹ā°
- Snāŗ: [Kr] 4d¹Ⱐ5s²
- As: [Ar] 4s² 3d¹Ⱐ4p³
- As³āŗ: [Ar] 3d¹ā°
- Ti²āŗ: [Ar] 3d²
- As³āŗ: [Ar] 3d¹ā°
- Ti: [Ar] 4s² 3d²
- As: [Ar] 4s² 3d¹Ⱐ4p³
- K: [Ar] 4s¹
- Zn: [Ar] 3d¹Ⱐ4s²
- K: [Ar] 4s¹
- Mg²āŗ: [Ne] 3s²
- Zn²āŗ: [Ar] 3d¹ā°
- Ca²āŗ: [Ar] 4sā°
- Cr: [Ar] 4s¹ 3dāµ
Now, going back through the list and marking the atom or ion with the largest radius:
- Be: *
- Sn:
- Be: *
- F:
- F:
- Ti:
- Sn²āŗ:
- Snāŗ:
- As:
- As³āŗ:
- Ti²āŗ:
- As³āŗ:
- Ti:
- As:
- K: *
- Zn:
- K: *
- Mg²āŗ:
- Zn²āŗ:
- Ca²āŗ:
- Cr: *
The atoms or ions with a star (*) next to them are the ones that are likely to have the largest radius among the options listed.
