WebThe element which has the largest atomic radius is Cesium. Atomic Radius is defined as the distance between the center of the nucleus and the outermost shell of an atom. Cesium has 6 orbital shells, which means that it automatically is big. See also Which is the richest country in Oceania? What is the atomic radius of all elements? Web8 de mai. de 2024 · Which element in a period has highest atomic size? As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest. Why do noble gases have smallest atomic radius?
