Surface Forms

transactinide positive

Morphology

transactinide = actinide (transparent) = trans + actinide

Formed by productive prefix 'trans-' meaning 'beyond' attached to 'actinide'; the meaning 'beyond the actinides' is directly derived, though the term is technical.

Etymology

Transactinide begins with trans-, as in transport, meaning 'beyond', and ends with actinide, the name for the group of elements after actinium. So transactinide means 'beyond the actinides', that is, relating to elements with atomic numbers greater than 103.
