Text Formatting ⇒ tikZ | Bad Math Spacing with circled Number

[ghostanime2001]

How can I have the 1 symbol behave like an expression like surrounded with $ $ ?
(btw I have already tried surrounding the tikz code in the preamble with $ $ and the spacing remains unchanged)

Code: Select all

{$#1$};}}

If I type \left(-1\right)\times\left(-1\right) in one line the spacing is correct as shown in the first picture below but when I use \left(-1\right)\times\ci{1} together with the ding symbol and type in one row I get different spacing as shown in the second picture.

Also I am trying to stay away from manually changing horizontal lengths because that would mean changing this for every equation I am going to type up.

This is my MWE for one of the type of formatting:

Code: Select all

\documentclass{article}
\usepackage[version=3]{mhchem}
\usepackage{tikz}

\newcommand{\ci}[1]{\tikz[baseline=(char.base)]{\node[shape=circle,draw,inner sep=1pt] (char) {$#1$};}}

\begin{document}
  $\begin{array}[t]{@{}l@{}}
  \left(-1\right)\times\ci{1}
  \end{array}$
\end{document}
