But the low ionization potential suggests that lawrencium has one very weakly bound electron in the 7p orbital instead of the 6d.
Some chemists think the empty 6d orbital suggests that lawrencium shouldn't be in the third column of the periodic table.
The measured ionization potential supports the idea that lawrencium does "not belong at the end of the f-block but rather at the start of the d-block," says William Jensen, a chemical historian retired from the University of Cincinnati.
