Ionisation enthalpy order of group 13
WebIonization enthalpies show an irregular trend in the group 13 elements. As we move down the group, effective nuclear charge decreases due to the addition of new shells in the … WebIonisation enthalpy of the group 13 elements is not regular. Here is the order of the first IE of these elements- B > Tl > Ga > Al > In This irregular trend is attributed to d-block and f-block contraction. D-orbitals have a very weak shielding effect and f-orbitals even more so.

Webobserved discontinuity in the ionisation enthalpy values between Al and Ga, and between In and Tl are due to inability of d-and f-electrons ,which have low screening effect, to compensate the increase in nuclear charge. The order of ionisation enthalpies, as expected, is ΔiH1 WebIonization enthalpy is also decreased due to the shielding effect. Alkali earth metals have the lowest ionization enthalpies, especially when they are compared to the halogens. The ionization energy of lithium is 520, sodium 496, potassium 419, rubidium 408, cesium 376, and francium 398. Trends of Ionization Enthalpy in Group II
