下一个代码可以绘制为三维对象吗

{
\begin{minipage}[c]{.7\textwidth}
\vskip -15.cm
{
\begin{tikzpicture}
\draw [thin,orange,fill=yellow]
(.25,.25) --  (.25,0) --  (.5,0) --  (.5,.25) --  (.75,.25) --  (.75,.5) --  (.5,.5) --  (.5,.75) --  (.25,.75) --  (.25,.5) --  (0,.5) -- 

 (0,.25) -- cycle ;
\end{tikzpicture}
\vskip -.7cm
\hskip -.06cm
{{\textcolor{red}{{\huge{\textbf{{Na}}}}}}}
}
\end{minipage}
}

答案1

像这样吗？

钠

或这个？

更多 Na+

或这个？

进一步的 Na+
