Respuesta :
The first 3 electrons that enter into p orbitals must have A. Parallel Spins. I believe.
In p orbital, there are 3 subshells that can accumulate 6 electrons. The first 3 electrons can be accumulated in the shells based on the parallel spin.
The electrons have been filled in the orbital based on quantum mechanics. The electrons are filled in the shells by the principal quantum number, the subshells regarding the azimuthal quantum number, and the magnetic quantum number, and the spin quantum number that specifies the spin of the electron.
The spin has been assigned by following Hund's rule. The rule allows the electrons to be filled with the +ve spin followed by the -ve antiparallel spin.
In p orbital, there are 3 subshells that can accumulate 6 electrons. The first 3 electrons can be accumulated in the shells based on the parallel spin, and the next 3 electrons can be accumulated based on the antiparallel rule.
