Traditionalists maintain that these comprise scandium, yttrium, lanthanum and actinium; a growing number thinks that lutetium and lawrencium should replace the last two on the basis of electronic structures.

As calculations had predicted, relativistic effects make the ionization potential of lawrencium even lower, relative to its lighter homologue lutetium, than the usual periodic trends would imply.

Over the course of 30 years, his inventions contributed to the discovery of americium, curium, berkelium, californium, einsteinium, fermium, mendelevium, nobelium, lawrencium, rutherfordium, dubnium and seaborgium.

He articulates the case for putting lawrencium in the d-block in a paper he published in Foundations of Chemistry on 21 March2.

Scientists have made a considerable effort to identify the characteristics of 103 elements, from hydrogen to lawrencium, and explain the complexities of their interactions.
