- Given below are two statements:
Statement I: Aluminium is more electropositive than thallium as the standard electrode potential value of \(E^{\circ}_{\text{Al}^{3+}/\text{Al}}\) is negative and \(E^{\circ}_{\text{Tl}^{3+}/\text{Tl}}\) is positive.
Statement II: The sum of first three ionization enthalpies of boron is very high when compared to that of aluminium. Due to this reason boron forms covalent compounds only and aluminium forms \(\text{Al}^{3+}\) ion.
