HF has the highest boiling point among the two substances because of hydrogen bonding a very strong dipole-dipole ... Web14 de mai. de 2016 · The first ionization enthalpy of zinc is higher because it represents an ionization from the 4 s level. Now zinc does have an ionization enthalpy of 906 k J / m o l, which is higher than copper's 745 k J / m o l or nickel's 736 k J / m o l in the same series. But I am not sure that the reason for this increase stated in the book is correct.

WebExample \(\PageIndex{1}\): Highest Fourth Ionization Energy. From their locations in the periodic table, predict which of these elements has the highest fourth ionization energy: B, C, or N. Given: three elements. Asked for: element with highest fourth ionization energy. Strategy: List the electron configuration of each element. WebIt is because of the shielding effect that the ionization energy decreases from top to bottom within a group. From this trend, Cesium is said to have the lowest ionization energy and Fluorine is said to have the highest ionization energy (with the exception of Helium and Neon). 1 st, 2 nd, and 3 rd Ionization Energies
