Question: what is the total number of electrons possible in all of the 2p orbitals?
Answer: In general, a subshell is comprised of orbitals. In this particular case, the 2p-subshell contains three 2p-orbitals, 2px , 2py , and 2pz . You would say that a 2p-orbital is located in a 2p-subshell. If you go by number of electrons, each 2p-orbital can hold a maximum of 2 electrons.
