Page number with a symbol

Question

I am looking to put the page number inside the atom symbol, Is this possible? I have been looking for information on the web, but I can't find anything similar.

Answer 1

You can use the atom symbol from How to draw a symbol on a TikZ node that can be reused, adapted to print the page counter inside of the node.

Then, using fancyhdr, you can redefine the footer to use the new macro instead of the standard number (see for example Page numbers only on even pages). The table of contents is produced using the standard numbers.

\documentclass{article}
\usepackage[bottom=4cm]{geometry}
\usepackage{lipsum}
\usepackage{tikz}
\usepackage{fancyhdr}
\def\science{
\begin{tikzpicture}
\node[circle, draw, minimum size=10mm] at (0,0) {\tiny\arabic{page}};
\foreach \ang in {0,120,240}
  \draw[rotate around={\ang:(0,0)}] (0,0) ellipse (4.5mm and 1.5mm);
\end{tikzpicture}
}
\fancypagestyle{plain}{%
\fancyhf{}%
\fancyfoot[C]{\science}%
\renewcommand{\headrulewidth}{0pt}%
\renewcommand{\footrulewidth}{0pt}}
\pagestyle{plain}
\begin{document}
\tableofcontents
\section{Lipsum}
\lipsum[1-100]
\section{New section}
\end{document}
