Root Explanation
Transuranic → It is formed from "trans-" (meaning across) 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 term "transuranic" refers to elements that are beyond uranium in the periodic table, thus meaning across or beyond uranium.
Memory Tip
Think of elements that are 'beyond' ('trans-') uranium — that's what transuranic means.
