Root Explanation

Transuranium → It is formed from "trans-" (meaning across or beyond) and "uranium" (from the name of the element uranium, which is derived from the planet Uranus, named after the Greek god of the sky, Ouranos). The word "transuranium" refers to elements that are beyond uranium in the periodic table, indicating their position across or beyond uranium.

Memory Tip

Think of elements that are found 'beyond' ('trans-') uranium, which helps you remember that transuranium refers to those elements that come after uranium in the periodic table.
