Solution to the wave equation: Shape of Orbital within a shell
So far so good!
What should have been obvious is that you have a situation where, going back to the analogy, a drawer can have more than one folder (all shells except n=1 contain more than one subshell), and also that a folder can contain different number of information (subshells such as p, d and f can contain more than one orbital).
In other words, electrons in atoms are found in orbitals.
Three questions arise then:
Firstly, how are the orbitals in subshells within the same shell  (s, p and d in n=3 for example) distinguished from one another? Secondly how are orbitals within the same subshell (the three p orbitals in p subshell in n=3) differentiated? And lastly, how are orbitals in different shells (for instance the s orbitals in n=1 and n=2) are different from one another?
