Summary[edit]
DescriptionF-block elution sequence.png |
English: Elution sequence of the trivalent lanthanides and actinides from a Dowex 50 cation‐exchange resin column at 87 °C, using ammonium α-hydroxyisobutyrate (ammonium α-HIB) as the eluant. The broken curve for element 103 (Lr) shows an estimate based on its predicted atomic radius, as its half-life is too short to confirm its position in the elution sequence. |

Public domainPublic domainfalsefalse |
The depicted text is ineligible for copyright and therefore in the public domain because it is not a “literary work” or other protected type in sense of the local copyright law. Facts, data, and unoriginal information which is common property without sufficiently creative authorship in a general typeface or basic handwriting, and simple geometric shapes are not protected by copyright.
This tag does not generally apply to all images of texts. Particular countries can have different legal definition of the “literary work” as the subject of copyright and different courts' interpretation practices. Some countries protect almost every written work, while other countries protect distinctively artistic or scientific texts and databases only. Extent of creativeness, function and length of the text can be relevant. The copyright protection can be limited to the literary form – the included information itself can be excluded from protection.
