WebThe atomic radius trend describes how the atomic radius changes as you move across the periodic table of the elements. In general, the atomic radius of an element tends to increase as you move down an element … WebDec 7, 2024 · The atomic radius increases down a group because as you move down, each group gains a shell, therefore the atomic radius increases as the atom gets larger. note- as you move across a period, there are no shells being added, for elements in the same period all have the same number of shells. Top. Akshat Katoch 2K.
WebAtomic Radius is a term describing the distance between an atom’s nucleus, and its outermost electron shell. Several factors affect this distance; including the number of an element, and the number of electron shells. Through Periodic trends, the atomic radius increases in size further left of a period, and lower down a group.
