So I had this chemistry question: Write the shorthand notation for all hydrogen orbitals that belong to the n=4 principal quantum number energy level. What property do they all have in common.
To me it sounds like it's asking what orbitals occupy the fourth shell but I don't know what property they would share besides the fact that they occupy the fourth shell. But I may have it all wrong, so any help with this is appreciated.

What does mean shorhand notation? 4s 4p_x ...?
