The selection rules allow finding how many electrons there are in the p orbitals is:
Number of electrons in p-orbitals is 15Solving the equation for atoms in three dimensions gives three constants called quantum numbers, which are related:
Principal (n). It gives the energy of the electron and can have values from 1 to infinity. Orbital (l) or secondary. Determines the shape of the orbital, in general it is specified in letters: s, p, d, f and can have values from 0 to (n-1). Magnetic (m). It is related to the magnetic moment due to the movement of the electron around the nucleus, it can have values from - l to lThese relationships are called selection rules.
They indicate that the atom has 33 electrons, therefore they must be arranged according to the selection rules.

Electrons in p orbitals are:
quantum number electrons
principal p orbital
1 0
2 6
3 6
4 3
Total electrons 15
In conclusion using the selection rules we can find when electrons are in the p orbitals is:
Number of electrons in p-orbitals is: 15Learn more here: link
