Document Summary

Heisenberg uncertainty, limitations we"re unable to know. P orbitals are roughly dumbbell shaped (spheres across from each other): the exact arrangement of electrons is the electron configuration, rule 1: electrons occupy the lowest energy orbitals available. This is complicated by crossover of energies above the 3p level. Electrons fill orbitals from the lowest energy orbitals upward. Above the 3p level, the energies of the orbitals in different shells begin to overlap. Valance shell is the outermost electron shell of an electron.
