# Step by step drawing of Lewis diagram - how can I hide the bonds?

For a chemistry assignment I need to produce a few Lewis diagrams. It was very simple with a linear molecule where I replaced the bond lines with \quad, but then I had to draw a 3D molecule and when I tried to hide the bonds by setting their color to white, they developed through the electron dots to my dismay.

How can I show the first step in Lewis diagram w/o bond lines and preserve the dots?

\documentclass{standalone}
\usepackage{chemfig}

\begin{document}

\setbondstyle{white}
\schemestart
\chemfig{O=[:30]\lewis{2:5:7:,S}(=[::60]O)=[::-60]O}
\schemestop

\end{document}


Use \setbondstyle{draw=none} instead of \setbondstyle{white}:

Complete code:

\documentclass{standalone}
\usepackage{chemfig}

\begin{document}

\setbondstyle{draw=none}

\chemfig{O=[:45]\lewis{2:5:7:,S}(=[:90]O)=[:-45]O}

\end{document}
