Math & Science ⇒ Ions

[Robyn]

I'm using Texworks on a mac to write a report on negative ions. I was told to use \ion to write in my ions (rather than using eg. $H^{-}$) but it doesn't seem to be working. Is there any other way to include ions in my text?

Use package chemformula.

Code: Select all

\documentclass{article}
\usepackage{chemformula}
\usepackage{chemmacros}
\begin{document}
\ch{H+} is a hydogen ion


This is in text \ch{2 H+ + O^{2-} <> H2O}, but you can use it
similar to maths equations:
\begin{reaction}2 H+ + O^{2-} <> H2O\end{reaction}
\end{document}

Who told you that? As far as I know there is no package providing an \ion macro…
