Web3 Aug 2024 · Answer: Aluminum < Thallium < Indium < Boron Short Explanation: Ionization energy increases across a row (period) and decreases down the column (group) of the periodic table. Ionization Energies: Aluminum: 577.6 kJ/mol Thallium= 595.4 kJ/mol Indium: 1008.4 kJ/mol Boron= 1139.9 kJ/mol Thorough Explanation: A thallium atom has 81 electrons, arranged in the electron configuration [Xe]4f 5d 6s 6p ; of these, the three outermost electrons in the sixth shell are valence electrons. Due to the inert pair effect, the 6s electron pair is relativistically stabilised and it is more difficult to get these involved in chemical bonding than it is for the heavier elements. Thus, very few electrons are available for metallic bonding, similar to the neighboring elements mercury and lead. Thallium, then, like its con…
