Listen Why does an electron found in a 3s orbital have a lower energy than an electron found in a 3p orbital in multielectron systems There are more nodes found in the 3s orbital The shape of the orbital ultimately determines the energy of the electrons Electrons in the 3s orbital can penetrate the 1s orbital and be closer to the nucleus Electrons in the 3s orbital are shielded by electrons in the 3p The larger number of electrons found in the 3p orbital leads to greater repulsion
