How do electrons in an atom occupy shells, sub-shells and orbitals?

You know that the distribution of electrons in shells, sub-shells and orbitals in an atom is known as electronic configuration. Now answer the question by using the electronic configuration 1s^(2) 2s^(2) 2p^(1) How many sub-shells are there ? What are they ?

You know that the distribution of electrons in shells, sub-shells and orbitals in an atom is known as electronic configuration. Now answer the question by using the electronic configuration 1s^(2) 2s^(2) 2p^(1) How many shells are there? What are they?
