How many filled p-orbitals are there in a Ne atom?
Ne (Z = 10) is a neutral atom that has 10 electrons that will fill the orbitals according to the 'Aufbau principle' and by using the knowledge that (for the hydrogen atom) the energy of the orbitals increases as follows:
1s < 2s = 2p < 3s = 3p = 3d < 4s ...
Then when we analyze the electron configuration for Ne, we find that is 1s2 2s2 2p6, which means that only one p-orbital is filled with electrons.
In conclusion, answer B (1) is the correct one.
