Based on your knowledge of electronic structure and periodic trends, compare the energies of the 2 s orbitals for O and Which element has the 2 s orbital with the lower energy? Which element has atoms that would more easily lose 2 s electrons? Based on your knowledge of electronic structure and periodic trends, compare the energies of the highest occupied orbitals for O and S. Which element has the highest occupied orbital with the lower energy? Which element has atoms that would more easily lose an electron from this orbital? Based on your knowledge of electronic structure and periodic trends, compare the effective nuclear charge for B and F. Which element has the the lower effective nuclear charge? Which element has atoms that would more easily form cations
