  • Scientists at the laboratory are synthesizing new transactinide elements for further study.

  • Elements classified as transactinide are all radioactive and do not occur naturally.

  • The transactinide elements are fascinating to study.

Surface Forms

transactinide singular
transactinides plural

Morphology

transactinide = actinide (transparent) = trans + actinide

Formed by productive prefix 'trans-' meaning 'beyond' attached to 'actinide'; the noun sense directly denotes elements beyond the actinide series.

Etymology

Transactinide comes from trans-, meaning 'beyond', and actinide, named after actinium, so a transactinide is an element 'beyond the actinides' and is usually made in a lab with an atomic number greater than 103.
