I was studying atomic orbitals and always had this question lingering.
As we can see in the image, the 1s and 2s subshells both are known to closely surround nucleus. The overlapping peaks in the graph (of probability vs radius) lead me to believe that the part region of 2s before the node should overlap with the region under 1s.
And by 1s and 2s I mean their contours ( regions which contain 90% probability of electron occurring).
Am I committed a blunder here or do subshells overlap?
Additionally, does the same logic apply when comparing the spatial distribution of say 2p and 2s aswell? Do they have overlapping regions of high electron probability density as well?
