Hi list,
I’m writing nuclear reactions. When add prescripts to atomic symbols with two letters, (Be, Sr, Xe, etc.) the prescripts split the atoms! (See output below.)
\starttext
Text: \lohi[left]{4}{10}Be.
Reaction:
\startformula
{\rm U}^^{235}__{92} + n \rightarrow {\rm Sr}^^{94}__{38} + {\rm Xe}^^{140}__{54} + 2n
\stopformula
\stoptext
I looked at \chemical and \molecule, but could not find a way to make isotopes with those. Any ideas?
Gavin

But I found something that works for my current needs: \define[1]\Sr{\mathord{\rm Sr}__{38}^^{#1}} \define[1]\Xe{\mathord{\rm Xe}__{54}^^{#1}} \define[1]\U{\mathord{\rm U}__{92}^^{#1}} \starttext Reaction: \startformula \U{235} + n \rightarrow \Sr{94} + \Xe{140} + 2n \stopformula \stoptext Since I will be writing many reactions with a dozen or so different atomic symbols, it makes sense to create a command for each atomic symbol that adds the correct atomic number and takes the mass number as an argument. Hope someone else can benefit. I still getting used to ConTeXt's treatment of {…}, which does not appear to be TeX's way.

From the chemical manual: As in mathematical typesetting mode, subscripts and superscripts can precede text. Thus, isotopes (such as this alpha particle, for example), can be written as: \chemical{^4_2He^{2+}}. But compare the alignment of \chemical{_{92}^{238}U} with \chemical{\lohi[left]{92}{238}U}. I have not used chemical formulas for some time, but \chemical{^{235)_{92}U,+,$n$,->,^{94}_{38}Sr,+,^{140}_{54}Xe,+,$2n$} "->" and "GIVES" are synonyms, as are "+" and "PLUS" (also MINUS, SINGLE, DOUBLE, TRIPLE, EQUILIBRIUM, MESOMERIC with ascii and unicode synonyms). Alignment can be altered using \lohi[left]{92}{235} (remember left is flushright) There is also "display mode" for chemical formulae: \startchemicalformula \chemical{text} \chemical{text}{below} \chemical{text}{above}{below} \stopchemicalformula where above and below can be used for labels, etc. Alan ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 5+ messages in thread

One can use Unicode superscript and subscript numbers, as in ²³⁵₉₂U, which is easier to read.
