How can I draw s and p orbitals to match the style or format shown in the attached image?

Question

I need to draw s and p(x, y, z) orbitals as shown in the attached image color doesn't matter for the orbital. My code is as follows:

\documentclass{article}
\usepackage{tikzorbital}
\begin{document}
\begin{center}
    \begin{tikzpicture}
    \orbital[pos = {(0,1)},scale=2.5]{s}
    \node[below] at (0,0.2) {orbital shape $\ell=0$};
    \orbital[pos = {(5,1)},scale=3]{px}
    \orbital[pos = {(5,1)},scale=3]{py}
    \orbital[pos = {(5,1)},scale=3]{pz}
    \node[below] at (5,-1.5) {orbital shape $\ell=1$};
\end{tikzpicture}
\end{center}
\end{document}

The code gives the following results:

The chemmacros package offers s,p and sp-hybrid orbitals (based on TikZ): Easy way to draw atomic orbitals and integrate them into ChemFig structures
