- Whose sentence?

- (but obviously in a very convolved manner)

"Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa quae ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo. Nemo enim ipsam voluptatem quia voluptas sit aspernatur aut odit aut fugit, sed quia consequuntur magni $$\frac{a}{b}$$dolores eos qui ratione voluptatem sequi nesciunt. Neque porro quisquam est, qui dolorem ipsum quia dolor sit amet, consectetur, adipisci velit, sed quia non numquam eius modi tempora incidunt ut labore et dolore magnam aliquam quaerat voluptatem.

Which can be modelled by


 * 2 Na + 2 H2O → 2 NaOH + H2

Furthermore this sentence is self referential. From Manual of Style/Chemistry,


 * Isotopes should be labelled by their mass number, e.g. 14C and 18F.

Holmium is an element in the f-block of the periodic table.\

Characteristic of Lanthanides, Holmium has a small crystal field splitting, and a sharp electronic spectra in comparison to the d-block metals, prefers an anionic ligand with high electronegativity atoms, do not form double or triple bonds with oxygen or nitrogen, do not form stable carbonyls, and do not have chemistry at the zero oxidation state (Cotton).

Holmium has a 1.3 ppm abundance in the crust with respect to Silicon, and a 0.9 ppm abundance in the solar system with respect to Silicon. In lanthanide ores, 0.05% in Monazite, 50 ppm in Bastnasite, and 2% in Xenotime.

The table derivable from Mendeleev's Periodic Law places Hf after La, and Pb after Ti. The fifteen lanthanoids La though Lu were only theoretically grouped by Moseley and Bohr. Bohr claimed that the fourth quantum shell could accomodate 32 electrons, where the lanthanides places electrons into the 4f orbital.

By definition, lanthanoids are elements whose 4f orbitals are gradually filled. This begins with La, and ends with Lu.

From La to Lu, the general trend of atomic radius is to decrease. From La to Lu, the probability density function of the 4f orbital of each lanthanoid may illustrate this decrease in radius.

The introduction of the minute hand into watches was possible only after the invention of the hairspring by Thomas Tompion, an English watchmaker, in 1675.
