Math & Science ⇒ chemmacros | Correct Alignment for Oxidation Number

[ghostanime2001]

How do you make the oxidation number center itself in the center of each chemical element? If you take a closer look at the chemmacros package, the oxidation number is moved slightly to the left.

Try this:

Code: Select all

\documentclass{article}
\usepackage{chemmacros,etoolbox}

\begin{document}

\ox{2,Ca}

\ExplSyntaxNamesOn
\patchcmd{\chemmacros_ox:nn}{\rlap}{\clap}{}{}
\ExplSyntaxNamesOff

\ox{2,Ca}

\end{document}

How can you use this for multiple oxidation number assigning on the same molecule but on a different atom ?

[cgnieder]

I'm not sure I understand what you mean...

Code: Select all

\documentclass{article}

\usepackage{chemmacros}

% patch chemmacros:
\usepackage{etoolbox}
\ExplSyntaxNamesOn
\patchcmd{\chemmacros_ox:nn}{\rlap}{\clap}{}{}
\ExplSyntaxNamesOff

\begin{document}

Calciumsulfate:
\ch{"\ox{2,Ca}" S "\ox{-2,O}" {}4}


\end{document}

[ghostanime2001]

oxidation numbers of more than one atom in the same molecule. For example H and O in water

[cgnieder]

Yo can just use the \ox command repeatedly. Or do you want the numbers in a structural formula? In the latter case I'd use chemfig.
