Document Summary
Rank li, be and b in terms of increasing electron affinity and ionization energy. Be, li, b: effective nuclear charge causes it to increase as you go right on the periodic table due to effective nuclear charge. However be and li are reversed because of the stability caused by the fully filled orbital in be. Quantum numbers: state whether each set of quantum numbers is allowed. If they are, give the missing quantum numbers, state how many orbitals and how many electrons are present with those quantum numbers. (book/sapling/class/reviewsheet) Why does electron affinity have p-block exceptions: number of electrons, number of electrons, number of orbitals? l=4 ms= +1/2. In both cases they are based on the effective nuclear charge. Electron affinity is not only based on effective nuclear charge but also on stable electron configurations. (they may also say something like thing, stable half shells change electron affinity but not electronegativity).
