我必须用葡萄牙语的化学元素名称制作一个大表格。我正在使用该elements包来执行此操作，但没有成功。下面是几个示例。
\documentclass{article}
\usepackage[english]{babel}
\usepackage{elements}
\begin{document}
Result: \elementname{Na} \par
\end{document}
生产
\documentclass{article}
\usepackage[ngerman]{babel}
\usepackage{elements}
\begin{document}
Result: \elementname{Na} \par
\end{document}
生产
\documentclass{article}
\usepackage[portuguese]{babel}
\usepackage{elements}
\begin{document}
Result: \elementname{Na} \par
Expected: Sódio
\end{document}
生产
我能怎么做？
答案1
正如 moewe 所说，没有葡萄牙语翻译。不过很容易提供一个。我以法语为模板，从本网站（我不是化学家，所以我不知道这是否正确）并使用了一些正则表达式替换重音符号。将此文件保存为elements_names_portuges.def（不是portuguese）并放在 TeX 可以找到的地方：
