# What is the position of electrons inside the orbitals such as s-,p- etc?? I mean I know that they are in these spherical(s-orbital) and dumb-bell shaped(p-) but where do they actually lie?

The wave function $\psi$ tells you the state of the quantum particle, and ${\psi}^{\text{*}} \psi \mathrm{dx}$ tells you the probability of finding the particle in the interval $\mathrm{dx}$.
So, the $2 p$ orbital here has more electron density where it is darker. That means it is more likely that an electron is found in the darker regions.
