Alright so as it is known, trans-uranic elements are universally unstable. However, in this setting, I'm using forms of quark matter that can imitate the nucleus of transuranic elements at least mass wise and chemistry wise. Now, let's assume these elements behave chemically and physically identical to trans-uranic elements but are entirely stable. Now if they were abundant enough and incorporated into some form of biochemistry, what would be their roles and/or the advantages of using them?
Note: The aufbau principle has collapsed around these atomic numbers, as far as I can tell that implies energy levels have been rehashed and so some or several of these elements would be chemically similar.
Also, some trends like decreasing electronegativity in group 1 alkali earth metals get reversed after caesium.
Edit: Thanks Sean O'Conner for the first answer, but to update, some of the superactinide series like Unbibium (Z = 122) will possess a main oxidation state of 4+ and Unbihexium (Z = 126) will possess potential oxidation state of 8+ and a main oxidation state of +4, with +1,+2,+6 and +7 as other states. Furthermore the +3 oxidation state alone is only predicted in 5 out of 20 elements, so I think the answer is incomplete when it comes to superactinides.
Edit: apparently one element is predicted to have a main state of +12
