Polymer: Dots at the ends aren't in the middle

So currently it’s looking like this:

Here’s the minimal code:

documentclass[a4paper, 12pt]{scrartcl}

usepackage[ngerman]{babel}
usepackage[utf8]{inputenc}
usepackage{amsmath}
usepackage{chemfig}

begin{document}

As you can see the dots on the right are a little bit lower than the electron-connection on the left, next to it. Do you have an idea how I can fix that?
