The order of the orbitals is shown in the picture attached. This ordered arrangement is a guide to know the electronic configuration of a certain element. You can't skip an orbital, that's why 5s after 2p orbital is not possible. For element b, count the exponents of each orbital because they represent the electrons.
# of electrons = 2+2+6+1 = 11
Element 11 in the periodic table is
Sodium
(Na).
