There are two orbitals that are completely filled in this atom: the 1s orbital with 2 electrons (1s2) and the 2s orbital with 2 electrons (2s2). The 2p orbital is not completely filled, as it should have a total of 6 electrons (2p6).
That would be 1s2, 2s2, 2p6 are the 3 orbitals that are completely filled. The other one is not filled because it only has 1 configuration. Hopefully this help....if not I apologize. *PUMA #4*
The column that contains elements whose electron configuration ends with d4 is the "transition metals" column. Transition metals have partially filled d orbitals in their electron configurations, typically with the d orbitals being filled first before the s and p orbitals.
Ground state electron configuration of zinc (Zn): [Ar]3d104s2.
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
Nitrogen (N) is atomic number 7, so has 7 electrons in the ground state. The configuration is1s2 2s2 2p3. From this, one can see that the 1s is full, as is the 2s. So, the number of completely filled orbitals is TWO.

because they have completely filled orbitals
Neon has completely filled orbitals, has stable electron configuration and hence neon atoms do not bind / join with each other.
In general, you use the Aufbau Principle which indicates the order in which the shells and orbitals are filled. You just have to learn it and then you can determine the electron configuration of the elements.
Helium has completely filled orbitals and is hence chemically inert.

Xenon has five electron shells.
The column that contains elements whose electron configuration ends with d4 is the "transition metals" column. Transition metals have partially filled d orbitals in their electron configurations, typically with the d orbitals being filled first before the s and p orbitals.
In Fe atoms, the 3d orbitals are partially filled. Iron (Fe) has an electron configuration of [Ar] 3d^6 4s^2, where the 3d orbitals contain 6 electrons.
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration.
Ground state electron configuration of zinc (Zn): [Ar]3d104s2.
