Root Explanation

Transactinide → It is formed from "trans-" (meaning across) and "actinium" (from the Greek "aktinos", meaning ray or beam, referring to the actinide series of elements). The term "transactinide" refers to elements that are located beyond actinium in the periodic table, thus meaning elements that are across from actinium.

Memory Tip

Think of elements that are located 'across' ('trans-') from actinium, which helps you remember that transactinide refers to those elements beyond actinium in the periodic table.
