  • Why does an electron found in a 2s orbital have a lower energy than an electron found in a 2p orbital in multi-electron systems?
    • Electrons in the 2s orbital are shielded by electrons in the 2p
    • There are more nodes found in the 2s orbital
    • Electrons in the 2s orbital can penetrate the 1s orbital and be closer to the nucleus
    • The larger number of electrons found in the 2p orbital leads to greater repulsion
    • The shape of the orbital ultimately determines the energy of the electrons
