Is the chemistry of lawrencium peculiar?
It is explicitly verified that the atomic 7p(1) ground-state configuration of Lr originates from relativistic effects. Without relativity one has 6d(1). All three ionization potentials IP1-3 of Lr resemble those of Lu. Simple model studies on mono- and trihydrides, monocarbonyls or trichlorides suggest no major chemical differences between Lr and the lanthanides.
