How many electrons are present in a 4p orbital?
In fact, any orbital, regardless of its energy level, subshell, and orientation, can hold a maximum of two electrons, one having spin-up and one having spin-down.
This is the case because according to the Pauli Exclusion Principle, two electrons located in an atom cannot share a complete set of four quantum numbers.
To the level of an orbital, this comes down to one of the two electrons that share an orbital having spin-up, which is given by the spin quantum number
Since each of those
#3 color(red)(cancel(color(black)("p orbitals"))) * "2 e"^(-)/(1color(red)(cancel(color(black)("p orbital")))) = "6 e"^(-)#
Therefore, you can say that a
