If we look at the correct electron configuration of the Nitrogen (Z = 7) atom, a very important element in the biology of plants: 1s 2 2s 2 2p 3. We can clearly see that p orbitals are half-filled as there are three electrons and three p orbitals.

7f atomic orbitals. For any atom, there are seven 7f orbitals. The f-orbitals are unusual in that there are two sets of orbitals in common use. The first set is known as the general set, this page. The second set is the cubic set, this page and these might be appropriate to use if the atom is in a cubic environment, for instance. Three of the ...
An atomic orbital is a mathematical term in atomic theory and quantum mechanics that describes the position and wavelike behaviour of an electron in an atom. A maximum of two electrons, each with its own spin quantum number s, will occupy each of those orbitals.
f orbitals At the fourth and higher levels, there are seven f orbitals in addition to the 4s, 4p, and 4d orbitals. Counting the 4s, 4p, and 4d orbitals, this makes a total of 16 orbitals in the fourth level.
The 1 s orbital at the bottom of the diagram is the orbital with electrons of lowest energy. The energy increases as we move up to the 2 s and then 2 p, 3 s, and 3 p orbitals, showing that the increasing n value has more influence on energy than the increasing l value for small atoms.
In this picture, the four valence orbitals of the carbon (one 2s and three 2p orbitals) combine mathematically (remember: orbitals are described by wave equations) to form four equivalent hybrid orbitals, which are called sp 3 orbitals because they are formed from mixing one s and three p orbitals.
