use arrows in order to illustrate the occupation of p- orbitals by 2 and 5 electrons?

Answer 1

There are three p orbitals, labeled p_x, p_y and p_z, each of which can contain two electrons. The Pauli exclusion principle states that two electrons can only occupy the same orbital if they have different spins, denoted by up arrows and down arrows. The orbitals are filled as follows:

1st electron: p_x [up arrow]
2nd electron: p_y [up arrow]
3rd electron: p_z [up arrow]
4th electron: p_x [down arrow]
5th electron: p_y [down arrow]
6th electron: p_z [down arrow]

To give an analogy, imagine a public restroom with six urinals. If someone was standing at the p_x urinal and nobody else was in the room, would you walk over and stand next to him at the other p_x urinal? Absolutely not! Only when three of the six urinals are filled would you be forced to occupy the other p_x urinal. That's the essence of the Pauli exclusion principle.

Answer 2

If in the p-orbital there are 2 electrons one goes in px and the other in py
If there are 5 electrons two goes in px , two in py and one in pz
