| 1. | Anyway, too little again about all ( even francium ).

| 2. | Would have thought francium, if not for its radioactivity.
|
| 3. | Taken from SUNY Stony Brook's Francium news page.
|
| 4. | Francium-221 has a half-life of 4.8 minutes.
|
| 5. | Cropped image of device used to trap Francium atoms.
|
| 6. | Germanium, Europium, Francium, and Americum, are some of the obvious ones.
|
| 7. | Some of these nuclides are very short-lived, such as isotopes of francium.
|
| 8. | I'll reread the ChemEducator entry, which focuses on the discovery of francium.
|
| 9. | Recently, Sprouse and his colleagues have analyzed trapped clouds of atoms of the element francium.
|
| 10. | Bulk francium has never been viewed.
