“…Let us mention some of these theoretical studies, to illustrate the interesting chemistry (and physics) that might be found with these SHEs. Indeed, the chemical behaviour of two SHEs has been found to differ from what was previously expected from them: copernicium, Cn (Z=112) [25][26][27][28][29][30] and oganesson, Og (Z=118) [31,28,[32][33][34][35].…”
